Hello,
currently, we're facing an issue with our VPN configuration:
In our main office, we have a Mikrotik Router with an L2TP/IPSEC VPN server configuration. This configuration works very well and mainly all clients are able to establish the VPN tunnel and are also able to connect via RDP to a server behind this router.
Our problem is, that we have a second office, where more than one client wants to connect to the VPN. The establishing of the VPN connection is also working fine for all clients. What is not working is the RDP connection. This is only working for one client, mainly this client who established the VPN connection at last. All these clients are behind a Fritzbox who's responsible for the DSL connection. We are using the integrated Windows 10 VPN Client.
Is there something wrong with the NAT configuration or should we install a second Mikrotik Router as a VPN client in our second office and use it as a gateway for these clients?
Thanks in advance
Thomas
