Hi, I'm looking to build a router/firewall/ips system. I have a DSL modem, then I can use a crossover to get to the box, and then I want to connect the box to a switch to the rest of the network. I'd like to do some things to it though, like have advanced firewall capabilities, good security, and I was thinking of using snort to filter packets, dropping things that look like exploits, drop advertisements, look for brute forcing on FTP and SSH, ping bombs, and such. I'd also like to do some traffic shaping, like under full load on the DSL line I'd like to be able to specify which computers get more bandwidth, etc. I'll be using a Pentium MMX machine with a 5 gig hard drive, cdrom, and 2 nics. Anybody know how hard this would be and have any suggestions?
Thanks in advance
