Hello community, hope you can help me.
We opened a new location for our company. The new location should use our NAV 2013 CU58 via NAVUserPassword authentication. At first we gave them a OpenVPN Client and the NavClient runs fine at the new location.
Now we established an IPsec Tunnel between our location and the new one.
Looking like this
Router at new location
VPNGateway and Clients at the new location net
For Testing, alls ports are open in both directions and routing through the VPNGateway ist set on the Clients at the new location.
Ping runs good in all directions Middle Tier and all Servers <----> new Clients
If we start the NAV Client, it shows the splash screen, makes the entry to the Active Session Table, but the Start Screen of NAV does not appear.
After round about 20 minutes the Nav client shows the error of a lost connection to the server.
What i've tried:
Disable all Addins for the Startpage and use a simple profile
Make entries at the Clients hosts-File for NAV-Server, DB-Server, DCs, Exchange, CA, Third-party-Archive in case of DNS issues
optimizing MTU for the tunnel
capture the net traffic to search for unresponded dns request or other
Rename the addin directory of the NAV Client to disable third party dlls
Checking Event Log at Server and Client
has anybody an idea what i can check addinially or did anyone know the start procedure of the client, so i can check step by step which part is failing?
