Hello, I have a new challenge of trying to map some IP's to a single IP but with a static port. Here is a sample. Given 1 externally public IP I need to publish the entire internal class C subnet worth of machines using their internal static IP address but mapping them to different ports. Each workstation has a TCP processing running on a fixed port. For all intents and purposes let's say it's SMTP. What I need to do, using the single static IP address is map out a single port for each server behind it. So, given 10.99.0.x it we want something like this 10.99.0.1:25 = 199.199.80.41:30001 10.99.0.2:25 = 199.199.80.41:30002 ... 10.99.0.250:25 = 199.199.80.41:30250 Is there a simple way to do this? Currently we have a pre/post routing line per entry. Is there a better way? Thanks, Gary Smith
