Hello,
In our organisation we have a IPSEC site-to-site VPN between our corporate Cisco ASA5510 and a Cisco ASA 5505 on a remote location.
The VPN works fine, traffic is send between the networks.
But on the remote location we have a windows server that creates a L2TP/PPTP VPN (port 16000) to another server on the corporate site.
The L2TP/PPTP VPN is not coming up. I can see that the traffic on port 16000 reaches the corporate site (in the logging on the ASA5510).
I already inspect PPTP on the both asa's. The routings are correct, traffice flows to both subnets.
Can it have something to do with MTU size?
Please advice...
