Hi folks. probably a FAQ but I'm struggling. I have an internet connection linked to eth1 and a LAN connected to eth0 I want to set up simple 1-to-1 NATing thus: x.y.z.141 == 10.1.1.141 x.y.z.142 == 10.1.1.142 x.y.z.143 == 10.1.1.143 so that incoming traffic to .141 goes to the right place. This bit I've sorted. but the problem I've got is how do I get the outgoing to appear to come from the correct IP address and not the normal IP addres of eth1 -- Gary Stainburn This email does not contain private or confidential material as it may be snooped on by interested government parties for unknown and undisclosed purposes - Regulation of Investigatory Powers Act, 2000
