I am a new user to experts exchange so if I miss out some crucial information then please forgive me. I am trying to perform port forwarding using Server 2008 to forward internet traffic coming into our network to an internal web server listening on port 8080 (as we already have another webv server sitting on port 80) What I am doing is:
loading up RRAS
going to IPv4
Right-clicking the NIC that internet traffic flows through and clicking properties
Clicking the 'Services and ports' tab
Clicking Add, giving the service a description, on this interface, Protocol TCP, Incoming Port: 80, Private address: <ip of the internet facing NIC>, Outgoing Port 8080.
However when I do this I get an error saying 'The special port already exists. Enter a unique special port.' I take this to mean that there is already a service using Port 80 which indeed there is but I cannot modify that one as the ports are greyed out and therefore inaccessible. Is there a workaround for this error, or should I be attacking this from another angle?
Thanks in advance,
