Can only open some ports?

I'm a bit of a Cisco newbie and I'm hoping someone can offer me a little assistance. I have a Cisco 851W which I have configured using SDM express. Everything is working fine with the device, with one exception. I am apparently only able to open certain pinholes in NAT.

I want to foward ports 80, 443, and 3389 from the WAN interface to a server on my LAN. But after configuring the port forwarding, I am only able to access the server on port 80. Ports 443 and 3389 remain closed. Any thoughts on why that might be? Thanks for your assistance.

Hi

Can you post the current running config of your router ?

Thanks very much for your reply. I'm not sure what I did to fix my problem, but it appears to be resolved now. Thanks just the same.
