Hi, No I´m not changing my provider. We have 3 subnets, one on the internetside (before the firewall) and two behind the firewall. Behind the firewall we use real ip-addresses and 10-nets (10.0.0.*) What I try to do is listening, if someone wants to connect to x.x.x.x I want the firewall to send the package to one computer behind the firewall real-or not real-address. In another email I read that this ip-translation is possible and the kernel of linux can do this. is this correct?? Egon -- Barfusz Egon jun.
