Author Routing Problem into the inner net through VPN Tunnel

Hello,

I spent a lot of time to allow the access through the vpn tunnel on our
inner net. But i wasn't successful. Can someone maybe give me a hint?

The structure is as follows:

VPN(VPN Client) -> 192.168.1.0 -> Firewall (IPTables) -> 192.168.2.0

I can ping from the 192.168.2.0 net to the outside and through the
tunnel, but the access through the tunnel is not possible. The logs on
the firewall show me, that the packets are going to the 2.0 net and back
again. But the session is not established. The Firewall was of course
opened for the testing. But nevertheless, i tried the following
structure to exclude routing failures:

192.168.3.0 -> 192.168.1.0 -> Firewall (IPTables) -> 192.168.2.0

I could ping and work through all nets.

I really do not know where the error is. Please give me some hints. I
would be very pleasant.

Regards
Adam Lucarz
