Sharing Internet with 3 nic's

I have 3 nic's,
  • (Internet) eth2 is connected directly to the internet and get its info from my ISP's dhcp.
  • (LAN) eth0 has the dhcp server broadcasting and has the static ip address and shares the internet with my wireless router
  • (LAN) eth1 has the dhcp server broadcasting, has the static ip, but the internet is not shared

So I have my dhcp server broadcasting for eth0 and eth1. I used firestarter to share the internet from eth2 to eth0. However Firesterter only allows sharing with one nic, I need to share with both eth0 and eth1. I have been trying to figure this out for a while and cant. Any help appreciated.

Ubuntu 8.10, Kernel 2.6.27-7

There is a problem with your IP addressing, unless itäs a typo. Both eth0 and eth1 share the same IP.

Oh, yeah, oops, I changed the ip address of eth1 to and the internet is still not being shared. I get an ip address from the dhcp server but cannot get any internet

Execute this script on your router and on your client. Read the error messages and follow the help links for the messages. If you still don't have success to fix it on your own post the contents of the output file created by the script.
