I'm trying to get my MASQing machine working but I am running into problems with the external forwarding. I have followed the current HOWTO on 2.4.x kernels (which I might add is in beta, so everything in it hasn't been coverted to IPTABLES). Basically I have verified everything up to the external forwarding. From an internal masq'd machine (windows) I can ping the ip of the local nic on the linux box, as well as the ip on the connection to the internet on the linux box. This shows that my internal forwarding is working. But, when I try to ping and outside address (just the ip, not the domain name..not even testing DNS yet) I can't get a reply. The HOWTO kinda leaves me high and dry at this point, saying that either my internet connection isn't working or my kernel isn't compiled with ICMP Masquerading. I have followed all the directions on what I need in the kernel so I'm pretty sure that is ok, and I know the net connection works because I can ping stuff, ftp, login telnet, etc. Does anyone know what I can do to fix this?

P.S. My external connection is ppp0 (adsl).

thanks in advance,
nick

He may mean the how-to is in a beta stage (how most linux how-to's are). Have you turned on ip forwarding in the kernel?
