Hi, I just cant get NET to work. Here is my situation box one has address 192.168.0.1 two 192.168.0.2 other set defaultroute to one connect using ppp (some times ppp1 or ppp0 depend on available interface at time of connection) box one connect to the internet using dial-up (dynamic IP address) both two boxes running Linux, Box one run kernel 2.4.4-pre4 The thing is, untill now I can only used the backward compatibilty (using ipchain.o) , it is okay. I tried to use NAT, to day here is what I did modprobe iptable_nat (no error message, modules load ok) iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE it says No chain/target/match by that name of course it doesn't work I tried several susgestions in the NAT-HOWTO but no result. Please help me out as I feel that using ipchain with kernel 2.4 is not so good.... thank you
