Cisco 887VA port mapping issue

Hi,

I'm pretty new to IOS configuration and am having some difficulties mapping some external ports to hosts on the inside of the network.

I have gone through the steps that I expected would work and the hosts on the inside of the network can connect to the outside world and the results of internal to external mappings are present as expected while viewing the debug information.

What is also interesting, as depicted here, is that the static mappings are showing in the transactions table:

tcp 1XX.1XX.1XX.1XX:19770  2YY.2YY.2YY:3389    ---                   --- These are as configured.

When I attempt to connect to the address using the external port I am not seeing any evidence in the logs that point to the attempted translation being made.

Here is my complete config:

Yep its a terrible hackjob and I am sure there are a few commands that dont belong any more but I'm perplexed as to what I have missed.

Can anyone help point me in the right direction?

Thanks!

Cisco 887VA port mapping issue

Under dialer 1 remove ip access-group, ip inspect, ip mtu, and ip tcp mss adjust.

The latter has to be 1452 under vlan 1 only.

That shuld be enough.

The longer you work with Cisco, the less commands you will use.

Thank you for the nice rating and good luck!
