SSL VPN / no internet Access after 15 Min

XG firmware: SFOS 19.0.1 MR-1-Build365

 

Hello,
Internet access in the SSL VPN full tunnel breaks off after about 15 minutes during use. Only the firewall management page can be accessed. Internal servers or IPs cannot be reached!

Nothing can be seen in the log (firewall, web protection)!

So the tunnel is not separated, only the Internet access is terminated after 15 minutes without logging anything!

The whole thing was tested with Android 12, 13, OPENVPN version 2.5.036 and Sophos Connect version 2.2.75.0506!

can you please suggest what i could try to fix the problem?

Many Thanks

  • I suspect that clients that are in a network with a fritzbox on their (remote) side will run into trouble with that configuration.

    anyway:

    what is the tun1 interface for? The DHCP Server on XG is configured for 192.168.178.0/24 while tun0 has 192.168.178.0/25 and tun1 has 192.168.178.128/25

    That at least is a misconfiguration and if it does not work the traffic is sent to tun1 while tun0 is used in working situation.
