Routing problem with my dial-up connection

[theMagus]

Hi, I am a novice to linux and I can't solve this problem: I have a ppp0 connection to my ISP. I configured it, and everything works ok from FC2, but I can't access the Internet from a computer in my LAN. The ping works between computers, so the network it's well configured. I guess it is a routing problem. I read everything I could find about this but to no luck. What can you suggest?

it sounds like a DNS problem to me, give the contents of /etc/resolv.conf

Edit the file "/etc/sysctl.conf"

Change the line
net.ipv4.ip_forward = 0
to
net.ipv4.ip_forward = 1

and then reboot the system.
