I have a simple lab-environment with a Win10 client, a RRAS-Server and a RADIUS Server (both 2019) to demonstrate a PPTP-VPN. I setup the RRAS-Server as a RADIUS client on the server and set up a network policy (translated from german) to allow access for the "Domain-Users" group with MS-CHAP-v2. Now I can't connect from the Client (Code 629 in the event log) and the RRAS-Server logs event-IDs 20271 and 20255, along the lines of "Connection denied due to a policy configured on the RAS/VPN-Server".
The strange thing is that the RADIUS-Server does nothing: no event-log entries, no accounting file being created and using Wireshark I see access-request messages from the VPN-Server to the RADIUS-Server, but no replies. I triple-checked everything: RADIUS-Client configuration, Firewall and User settings, authentication protocols, the details of the access-request messages, everything seems fine.
The RADIUS server has some other roles: file server, DFS, FSRM, DeDup, DHCP, DNS, WSUS. Could this be an issue? Any other ideas?
Thanks in advance!
