VPN Established but no access to the internal network resources

I have a Cisco Router 2921 which i am using to establish a VPN Connection to a remote site. I would like to access the internal network but most especially the server ip 192.168.90.222. I have managed to establish the vpn connection and i have also been able to ping the internal interface 192.168.90.1 but i cannot reach, ping or remote desktop the server and any other resources.

My Current Config looks like this;

crypto isakmp policy 100
 encr 3des
 authentication pre-share
 group 2
!
crypto isakmp policy 101

I wonder what is missing in my config. Please help?

Hi,

Can the router itself ping the rdp server?

Is the router the default gateway for the rdp server/other resources? If not do they have a route to the VPN Pool Network?

Temporally test without Nat enabled

 

Thank you Rob for your reply. I really appreciate.

 

The router can ping the rdp server.

The router 192.168.90.1 is the default gateway for the internal network and all the resources.

 

Thank you

you have followed the same example as below :

 

http://www.firewall.cx/cisco-technical-knowledgebase/cisco-routers/809-cisco-router-vpn-client.html

 

couple of question :

 

do you have Firewall enabled on Windows Server?

can you locally RDP to Server?

Hi Bandi,

Yes i used that example as i was configuring the VPN on my Cisco Router.

 

Yes i have a firewall enabled on the Windows Server.

 

And i can rdp to the server locally.

 

But still i can't seem to access it over VPN.

Yes i have a firewall enabled on the Windows Server.
