I assume that you are trying to RDP to 192.168.1.2 and it's failing through VPN. If this is correct, it is not supported because you have the following configuration:

ip nat inside source static tcp 192.168.1.2 3389 interface FastEthernet4 3389

If you remove the above line, you should be able to RDP to 192.168.1.2.

Since you are configuring static port address redirection, you can't configure route-map to deny traffic towards the IP Pool subnet for VPN so it doesn't get NATed.

Please try to RDP to other hosts than 192.168.1.2, and advise if it works.

Hope that helps.

Jennifer Halim · ‎05-18-2010

Did you remove this line as advised:

ip nat inside source static tcp 192.168.1.2 3389 interface FastEthernet4 3389

??

And have you tried other ip address than 192.168.1.2 for RDP as advise earlier?

Arup Dutta · ‎05-18-2010

hi,

i have remove the line from my router

no ip nat inside source static tcp 192.168.1.2 3389 interface

FastEthernet4 3389

waiting for your reply

Jennifer Halim · ‎05-18-2010

Please add the following:

interface Vlan1

ip tcp adjust-mss 1380

Did you clear the translation after removing the "ip nat" line earlier?

Also, please try to RDP to a different ip address.

Davin Dameron · ‎05-16-2012

Jennifer,

I was having a similar issue where I could connect with the VPN, could ping the server, but could not browse http/https on the server. The above change to Vlan1 also solved my issue. Thanks so much.

Jennifer Halim · ‎05-16-2012

Cheers Davin. Thanks for the update.
