Here's the situation. My ISP routes all C class to specific IP ( that IP is from another class)= and=20 I got cisco router who has that IP on whitch all C class is routed. On the other port of the cisco router all IPs of this C class are awaliab= le. Some poor attempt to graphicaly show you.. ISP's routing. C class -> some.ip.198 99.some.ip.198 ->binded at || CISCO || at binded<- C.class.ip.1 So the router just makes the whole C class awaliable ((that it gets on=20 99.some.ip.198)) out his other port with ip C.class.ip.1. Can this be done on linux using only (route2) ip tool? Without iptables. I'm thinking something like ip addr add 99.some.ip.198/32 dev eth0 (eth0 is the interface on witch th= e IPs=20 come in - the whole class) ip addr add C.class.ip.1/22 dev eth1 ip route add 99.some.ip.gateway I hope you understood this mess and can help me a bit. Tnx. -Martin
