RDP Issues with ASA 5505

Asked by tauseefg in Cisco PIX Firewall, Remote Desktop/Terminal Services

Tags: , ,

Hi All,

I in the process of currently implementing an ASA5505 firewall on our network. I am having two issues which may or may  not be linked together.

We need RDP and FTP access to 2 inside servers. 192.168.1.10 & 192.168.1.11. Please see the configuration below from the ASA. The issue is that right now I can not RDP to the public address specified even though the I can RDP to the servers internally.

The second issue is that when I set the servers with the static IPs defined above the servers stop getting out to the internet. As long as the servers are DHCP I have no problem with them getting out to the internet.
