Hello, I am fairly new here, this is my first post. I have been trying to tackle this issue on my own to no avail. I have a Cisco 1921 to replace our current router which is constantly freezing. We have a couple inside servers, one is a web server and application server which needs to be RDP'd to by a couple of clients outside of our network. I cannot get this to work no matter what. I know it's not the server's setup as when I plug the network back into the old router, it works just fine.
All clients have access to the internet, and I can successfully ping/resolve hosts from both the router and a client computer connected. I cannot, however, rdp using neither our public IP, nor our hostname. The hostname does resolve to our ISP assigned IP, but the server cannot be contacted, leading me to belive this is a NAT issue. My config file is below. Any help would be greatly appreciated. THANKS!

Hi,
What's the ip address of the RDP server?
It appears to be that 10.1.1.181 with RDP port 3389 is mapped to ip of G0/0 with port 3395, while somehow you also configured a destination nat (normally used for load share, but not in this case) to nat tcp 3389, 3395, and udp 10000-20000 to destination 10.1.1.5

Hi,
Can you do this:
no ip nat inside source static tcp 10.1.1.181 3389 interface GigabitEthernet0/0 3395
no ip nat inside destination list 100 pool RTP_FWD
ip nat inside source static tcp 10.1.1.181 3389 interface GigabitEthernet0/0 3389
Also why did you use a rotary pool ?
Regards.
Alain
