Since you're using Qvpn (IPSec) doesn't give the client an DHCP address from it's range. It's more like creating a site to site tunnel. So any packets orginating from your pc will be seen from the remote network as on a different subnet so your firewalls will need to be configured properly.
So lets say client ip address is 192.168.5.100 and remote network is 192.168.1.0/24 the source address will be see as 192.168.5.100 which is on a different subnet.
Also have you tried to access other things on your network via IP address not by name?
