I currently have a 2800 series router with firewall OS which NATs port 443 to my Exchange server (see below).
ip nat inside source static tcp (exchange IP) 443 interface FastEthernet 0/1 443
I would like to evaluate RDP (Terminal Services) for remote access on a Windows 2008 Box however RDP now uses port 443 which means when I connect through the router I get a certificate error as the OWA certificate is returned from the exchange box instead of the terminal services cert from the 2008 box.
I have port 443 open to any host on my external IP as below:
permit tcp any host (external IP) eq 443
Sorry if this is a bit simplistic I don't often work on Cisco equipment..
