Hi all, I have a little problem..... I use a Redhat 7.3 with kernel 2.4.20 . I have installed iptables 1.2.7a and patch o matic and recompilated the Kernel and it works. But the problem is when I launch this command: iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE That produced : Invalid Argument I have loaded first the modules but the result is the same!!! Can i help me?? Thanks a lot!!! Bye Matteo
