i have two servers in a network with fix ip's and both are accessable in the local network with his names "server1" and "server2". So far , so good.
When we access the network via VPN (IPSec) we are not able to access the resources of both servers, only via the ip-address...
I made some entries in DNS Plus (running on server2) but this does not help (in Primary Zone \ Forward Zone):
network.local => type NS, TTL 10800, server2
network.local => type SOA, TTL 10800, server2 
server1.network.local => type A, TTL 10800, ip-address
server2.network.local => type A, TTL 10800, ip-address
What is wrong?
