VPN client connectivity/routing issues

The following is the issue:

I have a router on and it works just fine, they have internet access and any other thing they need to work, i was given the task to allow the users to reach a server throug a vpn client so i added the upd and tcp ports to the access-list in order to make it work, i installed the vpn client and it works ok. But the vpn client assigns a DNS server that i cant reach from my network.
But if i install the vpn client in another computer outside my office or if plug my pc directly to the cable modem or ADSl i can reach that dns server, the issue is with the router(or at least seems to be the router). Just to clarify i didnt configure the router, i know this configuration sucks.
Basically i can't ping anything behind the other router from my office.

This is my show runn output:
