Change incoming port

Is there a way I can have traffic comming in on port 80 be changed to be changed to another port internally? This is what I am running into....

Webserver runs port 80

WSUS and OWA server NEEDS to run on port 80. WSUS wont function on anyother port. Can I tell traffic coming in on lets say 65.167.x.x:6590 to then be changed in the astaro to go to the server I forward that to on port 80?

Does this make sense? Thanks.

P.S. We cannot change the webserver port. Big Boss man wont allow it.

DNAT (destination network address translation)

Say everything that hits the external firewall interface on port 10380 tcp will be translated to 80 tcp on your OWA. So you only have to say your clients to use port 10380 instead of 80.

Using DNAT as NimmdirKeks suggests should work.

Hi, just add a DNAT rule:

Src = Any
Svc = Port10380
Dst = external interface

Translate destination to:
New Dst = Exchange Server
New DstPort = HTTP

And don't forget to add a matching packetfilter rule:
Src = Any
Svc = HTTP
Dst = Exchange
Action = Allow

than it should work.

Regards
Gert
