I have an issue with the VPN client of my 750S. This is the scenario:
My OpenVPN and Wireguard Server has the public IP address 10.20.30.40
Beside the VPN endpoints there are other services running on this public IP as well: eMail, a couple of websites (the IP is the entry point of my Webproxy) and so on.
The big issue is: When the 750S has an active VPN connection to my server, routing all the traffic through it, all clients behind the 750S can’t access any services which are using the same IP address 10.20.30.40! Even pinging 10.20.30.40 from any client behind the 750S does not work!
This happens if the OpenVPN client is used as well as if I’m connecting via Wireshark.
When the 750S does not create the tunnel but any devices behind the 750s (PC, iPad, iPhone) they all can also access all services on the same IP as the tunnel endpoint without any issues!
It appears as if the 750S blocks all traffic which is addressed to the same IP as the VPN server. This is a showstopper for me!
How can this be solved?
