Hello!
Does anyone have experience with Windows Server 2022 RRAS?
The VPN server configuration is ready, I can see in the event log that the connection comes in from an external address, but then it drops the VPN connection at the end.
Server event log:
EventID: 20209 "A connection between the VPN server and the VPN client xx.xx.xxx.xx has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47)." In the case of PPTP, both the client side and the server evnetlog refer to the GRE protocol. In the case of L2TP, it says that there is a problem with the VPN connection.
All firewall rules are set, the router is configured, but the connection is not established. What is interesting is that you can connect from a mobile phone with L2TP and I can see among the connections that it has received a VPN IP address.
The connection is successful from the phone with the same user. From a Windows desktop or notebook through different ISPs, the error is always the same. I uninstalled the antivirus and turned off the firewall. If I try to telnet to the address of the vpn server via 1723, it gets through.
There is no domain environment, no dhcp and dns servers on the server either. These are handled by the router.
Do you have any idea what could be wrong, what should I do differently?
Regards, thanks!
