Server not reachable from internal network when using portforwarding

[smallore_4plus]

Hi all,

i have newbie question. We have the following situation:

A brachnoffice in Hungary is connected to our headoffice in Germany via IPSEC-VPN. Everything is working fine, all necessary traffic goes through the tunnels.

But if i set up a port forwarding (port 443) on the Router (1812) in Hungary to a server in the hungarian network, i cannot reach the server over the internal network from Germany. The port forwarding is working but if i use a private address from internal just the used port is not working.

Do you have any hints for me??

Thanks for your help
