Here's a more comprehensive look at how I'm set up, it's not very complicated and it works really great. I can't imagine ever using a commercial router, Cisco or anyone else:

Code:

Linux computers------
                    |
SGI computers------Hub----Linux firewall w/ two NICS----Internet
                    |       |
(one) Sun computer---        --- Running Slackware 15.0
                            |
                            --- Running my website (Apache)
                            |
                            --- IPTables firewall (configured by me)
                            |
                            --- Running dynamic host configuration protocol (for guest's lappys)

As long as you run a separate firewall, even a cheaper SOPHOS firewall, your router will not be a security problem. Then you can eventually replace it with more enterprise network solution in the future. That is one of my current plans.

I'm sure you had fun constructing that but I wouldn't recommend it to random people. If you don't trust your ISP modem/firewall, I would recommend something like pfSense or OPNsense. I used to run pfSense on a PC Engines APU2C4 which is a passively cooled platform using only 5W I think. servethehome.com has reviewed countless mini PCs that will do fine as well.

Both pfSense and OPNsense come with a web UI, documentation and are actively maintained.

The Cisco 3600 series were last sold 20 years ago, and have been unsupported for 15 years. They apparently use up to 140W of power. I'm sure it was a fine choice in it's day, but just because OP wanted a firewall for his IRIX system(s) does not mean the firewall has to be of similar vintage as the IRIX system...

I agree, I am not very enthusiastic to run a 36xx router that has been out of support and since 2008, out of sale in 2003. There is a reason why these units sell for such a low price. Also it is rare to find an ISP that allows one to use a static IP address.
