Cisco ASA5520 - RDP to a server on another port
Posted on 2013-10-29
I have a static NAT configured with port 81 open.
static (inside,outside) 18.104.22.168 10.9.0.20 netmask 255.255.255.255
access-list Outside_access_in extended permit tcp any host 22.214.171.124 eq 81
access-group Outside_access_in in interface outside
Now if I open remote desktop, and try to RDP to this server on port 81 like below, it doesn't work.
If I open port 3389, it of course works. Is there a reason why I can't RDP to a server on another port. Has anyone ever experienced this? It works for me on other ASA's I have configured at other locations.
Its a windows server 2008 R2 server that I am trying to RDP too
