I use cards that function on the tulip module. I have several d-link cards that work just fine. Typically, just about any pci ethernet card should work. You can check Red Hat's Linux compatibility page if you want to be absolutely sure you buy somethin' that will work for you. You will need to set your linux machine up so that IPTables forwards packets out from your network to the net. You will also want to make sure you have the kernel options in /proc/sys/net/ipv4/ set to 1 for ipforwarding and the ip dynamic address hack. You can do so with the following commands in a terminal, there is also the /etc/sysctl.conf file to set it up but I forget the syntax as of this moment. echo "1" > /proc/sys/net/ipv4/ip_forward echo "1" > /proc/sys/net/ipv4/ip_dynaddr The above commands can be put into /etc/rc.local so that at boot your forwarding is setup for the kernel. IPTables requires a simple forwarding policy that looks something like the following for me at least on ADSL. It goes in the *filter section of /etc/sysconfig/iptables. -A FORWARD -i ppp0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT -A FORWARD -i eth1 -o ppp0 -j ACCEPT -A FORWARD -i ppp0 -j REJECT And you'll need these lines added to the end of the iptables file. *nat -A POSTROUTING -o ppp0 -s 192.168.1.0/24 -j MASQUERADE COMMIT The above rule is assuming your outgoing interface (the internet connection itself) is ppp0. For you it may or may not be this. It may simply be eth0 for you. Also, my forwarding rules may not work out of the box for you, because again, your actual internet connection may not be ppp0. It's likely eth0 or somethin' similar. If you have questions please let us know. HTH, Alex White
