i just finished redoing my router, altho it is a Beige G3, before that i
used a Umax C500 (200Mhz 603 mac clone) and a 8500/233 (and occasionally
with a G3 upgrade card) and havnt had any problems... it is rather
simple and straight forward to do... i would personally say just use one
10/100 nic since most high speed providers dont offer service that can
overwhelm a 10baseT connect(i use cable modem) it is pretty much install
YDL (3.x or 4.x) and then follow the IP-Masquerading faq (
http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/IP-Masquerade-HOWTO.html )

which you just need to figure out which ethernet interface it assigns
eth0 & eth1 to (usually builtin is eth0 and pci is eth1 ) and put the
two files you need to create ( /etc/rc.d/rc.firewall-iptables &
/etc/rc.d/init.d/firewall-iptables ) in their proper place and edit them
for your setup and reboot... and off you go... note, use the stronger
ruleset in section 6.4.1

it is rather simple to do, you just need to make sure when you install
YDL to make sure you allow ssh connections when it is asking about the
firewall...


sloopy.

p.s. if there is a need for a mini faq that is YDL specific i could
throw something together if requested... i had mine up and running in
less then 15mins not including the ydl install time...
