Read this carefully: A PIX IS A PC. THAT'S IT. They put some flash on it, a custom BIOS, and Ta Da! The difference in PIX products is how much memory they have, number and type of interfaces, processor speed, and availability of encryption co-processor boards (standard PCI cards, BTW.) Cisco is using more standard PC parts because it reduces their costs dramatically.

Further, the PIX just isn't a very good firewall.
The hardware is well-built but incredibly underpowered. The one we have at work is only 200mhz. I don't know how far that will scale, but, personally, I don't think I'd want to be putting more than about 5 megabits through it. And Cisco charges about 12,000 dollars for the PIX.(!)
The command syntax is really hard to figure out. It just makes no sense at all. The documentation on Cisco's site is excellent, but I always have to resort to cookbook examples, because I don't use it every day.
The default configuration is 'allow all outbound traffic and all inbound replies'. It is very hard to change this. If you want a fairly secure network, you shouldn't allow direct outbound connections, but rather only through a proxy device of some kind. If your security policy requires outbound connection restrictions, this is really awkward to implement with the PIX.
The PIX isn't a very good router, either. It doesn't support most of the 'real' IOS commands. You can do some routing with it, but it's not very flexible.
I've worked with a lot of firewalls and have done a lot of firewalling, and in my opinion, Linux with iptables is about the best thing going. You will have to spend significant learning time to figure it out, as the documentation is not very good, but once you do, you can do pretty much anything with it. Linux has always been a great router, and with the introduction of iptables, became a great firewall too. If you don't want to build rules by hand, there's a program called 'fwbuilder' that gives you a Checkpoint-like GUI. FWBuilder also speaks OpenBSD's pf and I *think* Checkpoint's firewall language, but I'm not sure about that last.
OpenBSD has a good reputation as a firewall. I used it at home for a couple years, but I have moved to Linux since then. The PF language is very clean and easy to read, and if you're just starting with firewalling, it can be a good first opensource firewall. However, there were big performance problems with OpenBSD's bridging firewall code in 3.0; it choked hard over about 25K connections, and past about 30 megabits it just froze up for random periods of time. Very frustrating. Linux on the same hardware (with the iptables bridging patch) handles over 60 megabits flawlessly. And going over 30k connections is trivial; you simply echo a large number into a variable in the
They may have fixed the performance problems in more recent revs of OpenBSD. 3.0 was the first release of pf, and I threw it into a monster production environment based on the OpenBSD team's reputation. The later revs may be much better, but as of 3.0, Linux absolutely destroys OpenBSD as a firewall.
There's one cool thing the PIX does that I haven't figured out how to duplicate manually. It has an 'established' command, which allows you to say: "If I open a command on port X, allow a return connection on port Y for a short period of time." This is useful, for example, for IRC, where you connect on port 6667 and an ident connection comes back in on port 113.
I asked about this feature on the OpenBSD newsgroups, and got scoffed at... according to them, it's more secure to leave the port open all the time to everyone than just to allow return connections from a host to which you have connected and only for a short period of time. Frankly, I think that's just stupid. It's the typical apologist reaction... "that's a dumb feature to ask for because it's hard to do". They'll say it's stupid until someone takes the time to implement it, and then suddenly that's the only way to go and any system that doesn't do that is obviously broken.
I haven't found that capability in the Linux iptables stuff either, FWIW. As far as I know, only the PIX does this, and I consider it a very useful feature. (you can sort of simulate it with some of the kernel modules for different protocols, but I haven't found a way to do an arbitrary set of ports).
If you can live without the 'established' command, though, I'd probably, overall, recommend the Linux/FWBuilder combo. If you want to learn more about firewalling, OpenBSD's pf language is a nice simple way to start.
And if you really want to spend money on a firewall, Checkpoint is a much better solution than the PIX. It has many enterprise-class features that the free alternatives lack, like good VPN support and great support for managing clusters of firewalls. The Nokia Checkpoint boxes are *really* cool; they are based on a custom BSD-derived kernel. They cost more than the PIX, but in my opinion are wildly better and well worth the extra.

You're right. It does allow direct connections. Why? Because it's a packet filter firewall, not a proxy server. Want a proxy server? Buy one. Don't buy the PIX.
Correct again. The PIX is not a router. It's a firewall. I don't want my firewall to be a real smart router. It shouldn't. It should block packets like a good little firewall.
As for speed, the different PIX models have different speeds. They have also rev'd up the speed. Sure, you bought a 200MHz model a while back, but my 515E is a 433MHz model. One of them does not cost $12K, I think we paid close to that for both of them to set up a failover cluster with the 3DES VPN accelerator and full 24x7x4 3-year warranty.
The PIX is actually a very good firewall. It's not exactly like IOS, but it's close enough. It handles our site-to-site VPNs very well and the cluster support is VERY good.

You are partially correct. PIX, however, do require activation keys for all their functionality.
The activation key (non-DES/3DES) comes preset in the 16Mb Flash card that you need to build this clone.
Incidentally, you may be able to get some support as a purchase of a replacement flash card gives you a new Cisco S/N for your PIX (when purchased as an upgrade to an old 520 for instance).
And last time I checked Cisco were issuing DES activation keys for free as long as you gave them a Cisco S/N, which you have on your 16Mb Flash Card.

However, this would in a multi-user environment. Opening an inbound port would require it to always be directed to the same machine.
That would of course cause ident to either give incorrect information or fail outright. Although I've never used that feature w/ Pix, I assuming it creates a conduit back to the originator's IP...which would only make sense.
Still, I don't see it as being particularly useful. I just wanted to point out that it might be useful, and simply opening an inbound port wouldn't equate to the same feature.

Piracy? Theft? (Score:2)
Secondly, the article never actually mentions stealing a PIX flash card. Someone that legitimately owns an older PIX could, after the warranty/support/etc had expired, remove the flash card from their PIX and "upgrade" the hardware for a little nicer firewall. If you acquire the flash card through illegal means, however, then that would be stealing. Cisco might even sell them! (doubtful, but I don't have time to check it out)
As far as intellectual property goes...you aren't reverse engineering anything. Everyone knows the Cisco PIX is just a PC with a floppy drive and some flash memory. It even tells you that when you boot a real PIX.
All you are doing is constructing your own.

Did you know that they have cut promotions to 3% per year? I'll do that math for you. As a Cisco employee you can expect a promotion every 33 years. Not that it matters because if you do get promoted all you get are stock options with no raise.
Did you know that they have their "active management" guns blaring at full speed? This means that the managers are forced to cut 5% of their staff every quarter. (In fairness, they seem to actually cut less than that). However, they have certainly reduced their staff by over 20% in the past two years. There aren't any slackers left at the company.

Could someone explain the controversy? (Score:2)
I read the linked page as how to build a PIX-like firewall by slapping some PC parts together and adding a legally-acquired Cisco flash card containing the software. Am I confused about the nature of the flash card? I saw it as something like noticing you could buy Macintosh roms out of an Apple repair parts catalog, and then writing a page saying "Build your own Macintosh clone by putting some standard hardware together and adding Mac roms that you buy from Apple". Sure, you've possibly annoyed Apple by avoiding paying a lot more for a real Mac, but as long as you get the roms legally, where is the piracy? You're not copying the roms, you're getting legitimate ones. They're even still legitimate if you get them on a secondary market like from a trashed motherboard.
If all you want to do is run an OS from a flash disk on a PC, you can get a 16 MB CF card for under $20 and a CF to IDE adapter for another $20 or so. So I figured that the $400 for the PIX flash card has to mostly be going towards acquiring the software legally. Am I misreading the article?
Cisco hardware is slow (Score:3, Informative)
I own a PIX 506 box and have worked on the 515 and 525 as well.
Both the PIX 506 and 515 use an Intel socket 7 200Mhz MMX processor without a cooling fan, they just have a heat sink. The system board is just an Intel, nothing special there. PIX expansion slots are PCI slots. The Ethernet interfaces use Intel eepro i82557 (or was it i82559?) chips, just like your Intel NIC in your desktop. Everything is really standard, except for the software that runs on the box.
For people who know Cisco hardware, they seem to recognize that the PIX series of firewalls are far faster than say a 3600 series router, or any of the older Cisco hardware. The PIX firewalls were acquired by Cisco when they bought Network Translation. Reference;
http://www.cisco.com/warp/public/146/
So when you are buying that $4000 3640 with 128MB of RAM to handle the 100K or so of Internet BGP routes, you are buying something with the processing power of an Pentium computer or less.
Here are some facts on the Cisco 3600 series;
3620 64MB RAM maximum, 80Mhz RISC processor
3640 128MB RAM maximum, 100Mhz RISC processor
3660 256MB RAM maximum, 225Mhz RISC processor
One of the major considerations for Cisco is that their equipment has to be really stable and heat tolerant. People love to treat Cisco hardware like old telco hardware and keep it out in a barn and stuff, in the damp air, with a bunch of dust, whatever. We should all know how Intel processors are in regards to heat. But even an old 200Mhz Intel MMX processor can run without a cooling fan.
Cisco router hardware, in general, is really slow and sucks for processor speed. Juniper has mopped Cisco all over the floor in the core Internet market in the last few years because of port density, processing speed, and packet forwarding latency. In comparison, you look at a Juniper M40 versus a Cisco 12012, and the 12012 looks like a huge POS, and I don't mean packet over Sonet.
One of the things about the Juniper routers is that they use Intel processors and SDRAM -- not much special there. The hardware is all completely custom, but they choose to ditch the Motorola and IBM processors for Intel. Packet forwarding processors are totally different than the core processors that we are talking about here, so I will leave them out for the most part. Still, Cisco uses a lot of off the shelf stuff in their routers and companies like Juniper have manufactured their own or applied existing stuff better to get the wire speed forwarding rates on all interfaces, with a backplane speed that is greater than the sum of all possible interfaces on a router.
Cisco does not really see themselves as a hardware manufacture, but instead as a software company. However, if they do not shape up and start making some really good hardware, they are going to get kicked out by Juniper as they start to climb down the ladder and come out with smaller more affordable boxes and spread out from their core and big-box offerings (think M-5).
Lately Cisco has released a few good new hardware. The 10000 series aggregation boxes can mux Sonet down to fractional DS1s, which is pretty hot, but these boxes are really hard to use these days because of the serious downturn in the market and the fact that a lot of DS1 customers have gone away. Old 7513s that ISPs have in stock with fractional PA-2T3s work fine.
In switches, Cisco has come out with the 3500XL and 3550XL switches, which are really great.
But most people out there have 2600s and 3600s. There are a lot of 2500s still in use too. Some things are starting to hurt Cisco though. It can take a minute or two for all of those BGP routes to get filtered out when interfaces flap. Cisco does not even offer any kind of SSH2 capability with ANY of their routers (to my knowledge), they only support SSH1 on special IOS versions and platforms. I really wonder if these routers, with their slow processors, can handle new stuff.
I wonder how this will effect an IP6 roll out. I remember working on some 3600s and IP6 some time back. They had issues, but I understand that Cisco has worked a lot of those out.
Oh well.
The moral of the story is that Cisco hardware is kind of slow and it shows. On the other hand, it usually gets the job done.
I need to go back to finding myself a job. Posting on Slashdot ain't paying the rent.
Anyone out there have a Juniper Olive image? I would not mind having one of those in my lab.
