2811 Router Forwarding Problem

Level 1

Can anyone tell me why I can't get into my private network using RDP from an outside PC. I believe I have it configured to forward 3389 to a PC on the internal network, but it can't find the host. Any ideas?

!This is the running config of the router: 10.4.167.252

___________

Replace the interface name with the IP address and use the keyword extendable.

Example,

ip nat inside source static tcp 10.4.167.100 3389 199.199.199.1 3389 extendable

Ahhh.....OK, I'll give it a try. Can't switch the line until later tonight, but I'll be sure to let you know what happens. So just to satisfy my curiousity, why do I have to specify the IP, if the interface is configured to use the IP I configured it for? Thanks again!

Because the extendable option, is not allowed when using the interface. You need to use the ip address.
