We've just bought an 1801 router and would like to forward traffic to internal servers based on the external ip address the traffic comes on. (We already have a block of 5 ip addresses from our broadband company)
External IP 1 (Port 80) -> Internal IP 1 (Port 80)
External IP 2 (Port 80) -> Internal IP 1 (Port 8080)
External IP 2 (Port 25) -> Internal IP 2 (Port 25)
Whats the best way to do this? Can this be configured using the SDM?
