Opening port 3389 on a Cisco 806 router

[jripp00]

I have a Cisco 806 router. Before I put it between the PC and cable modem I could remote desktop (port 3389) into the PC from outside the network. Now, since the router is on the network, only the telnet port is open from the outside. I did a port scan on my inside PC and it shows port 3389 is still open from the inside. I don't have any access list's on the router so I don't know why it's blocking that port. Any ideas?

Mostly 806 will get the public address from isp and do NAT for the internal privet netowrk. You need to enter "sh ip nat translation" to see the nat translation in detail at router side..

Here is the url which discuss "connecting cisco 806 behind non-cisco cable modem"

Now you can also do static port mapping to get access to inside network.

You can statically map port 3389 for a public ip address to the inside host ip address..

Ok, it works now. I used this command:

ip nat inside source static tcp 10.10.10.3 3389 interface Ethernet1 3389

Thanks again
