Virtual private networks / Re: ipsec is working but no communication is possible

« on: March 29, 2023, 11:15:07 pm »

Hi,
the other side of the tunnel is a Sophos SG105 with a dynamic IP address. If the communication in the tunnel is no longer possible, the ddns name can still be pinged, so I do not assume that we have a problem with the changing IP address.

Also a restart of the remote gateway does not lead to the connection enabling communication again.

Only the reboot of the OpenSense itself fixes the problem temporarily.

There are more VPN tunnels with the same setup on the same OpenSense and there the problem does not occur.

Virtual private networks / ipsec is working but no communication is possible

« on: March 29, 2023, 07:41:10 am »

Hi,
i have a opensense with 5 ipsec tunnels, everything works fine. But after 2 - 3 days, communication is no longer possible within one of the tunnels. However, the tunnel is still established. Reestablishing the VPN connection or restarting the ipsec service does not solve the problem.

After restarting the opensense, everything works again for a few days.
All other tunnels work permanently.

Anyone have an idea what this could be?

Regards Tim
