Hello NG,
I configured my Ras on a Win2003 R2 server, on the Router I can see that a
Packet arrives on Port 1701 (yes, it should be a L2TP/IPSec Connection). The
Packet is forwarded, but no response comes from the Server to the Router.
Anyone knows how to solve this??

Have you forward the port to the server? Can you establish the connection internally?

Good morning Robert,
yes, Port forwarding is activated for Ports UDP 500 and UDP 1701. Internally
the Connection works quite fine.

I had a Cisco PIX case like one. You may need to open the UDP port 4500 on the router.

Hi Robert,
Port 4500 is open now, but I'm getting Error 792 and if I change something I
get Error 789, so it's either not connectiong or the Comm is refused due to
something...
But I don't know what to do...

Hmm.. Could this be the Problem?
In Routing and RAS, when I select "IP-Routing" and "General" in the
Connection with IP Address, I click on "Show UDP Listener Ports" and it
doesn't list Port 1701 for the IP Address...
