Add virtual interfaces to your linuxbox, assign them the ip-addresses and create some forwarding-rules for your required ports # virtual alias on your interface. check man ifconfig and alter my # statements for your needs eq replace x.x.x.x with the correct values ifconfig eth0:1 x.x.x.x # This creates a duplicate interface of eth0 with a different ip-address # (x.x.x.x). To remove one, simply put it down with ifconfig eth0:1 down After that you've got an interface where you can bind your forwardingrules to. hth -fe
