Hi all, External interface: A.B.C.D Internal network: 10.21.3.0/24 Firewall/router: 10.21.3.254 One special host: 10.21.3.1
What I want is to allow outsite to telnet into my special host thru a different external port (not 23). Lets say 20023. So what I want is to map A.B.C.D:20023 to 10.21.3.1:23 But when I do this, I also need to 'map' the source address as 10.21.3.254 because the special host cannot answer to IP addresses other than 10.21.3.0/24 network (seems like it doesn't have a default gw). Shortly, from a given X.Y.Z.T external IP, I need to NAT something like this; X.Y.Z.T -> A.B.C.D:20023 will change as 10.21.3.254:[some nat port] -> 10.21.3.1:23 Can I do this? -Ali
