I have a Linux box and want to set it up as a gateway. There are two ethernet interfaces in the box. The kernel had been compiled with the masquerade option. Also, I type in ipfwadm -F -a masquerade -W eth0 -S 10.0.0.0/9 -D 0.0.0.0/0 .
However, I cannot use this Linux gateway and telnet or http to the Internet. Can anybody tell me what else do I need to do ?
