Hello,
I have a server with Windows server 2019 and the Remote Access role with the features: 'DirectAccess and VPN' and 'Routing'. The server has two NIC's, one connected to the internal network and the other one, via a router, with the WAN. The VPN uses the protocols PPTP and L2TP and it is possible to connect with the VPN over the internet.
For some users it is not possible to make a connecting with the VPN and after a lot of testing it seems that the server doesn't respond to certain IP addresses, for all protocols, pptp, icmp etc. The server has a firewall and Symantec endpoint protecting but none have a rule to block some IP addresses. In the log of the firewall I can see the incomming connect, for example a request for een ICMP ping but no response, the same for the PPTP, etc.
As far as I can see and know, there are no limitations for connections based on IP and I don't know what to check next. Are there other places in Windows Server 2019 where IP's kan be blocked?
Becasue we lost an server the Remote Access role is installed on a server that also acts as a back-up domain controller.
Thank you in advance for your time.
