Site To Site SSL VPN random disconnection

Hi everyone,

We have a cloud Sophos 19.5 appliance with a public IP. We use it to setup a site to site SSL VPN to another Sophos 19.5 with is located behind a 3rd party firewall.

For some reason, the VPN behaviour is erratic. It could work for few days, then it stoppes working (state is disconnected with the red circle on the SSL VPN S2S page).

Unfortunatley, no useful logs in the log browser (it just says the S2S VPN has been disconnected.)

After the disconnection, the VPN S2S is impossible to restart, The status remains red even if we restart the vpn from the server or client side.

What could cause such issues ? This is problematic for us as we are strongly relying on this feature

Thank you very much for your help

Cheers everyone !

Hi Vivek Jagad

Thank you very much for your answer !

I struggle a little bit to download the log files as I manage to access them via the cli, but the listing of the directory /log using winscp or filezilla is always empty.

Is there any settings to adjust to allow the log directory listing ?

Thanks

bs84567 , /log/sslvpn.log (from the cli) is the one to be looked at to have initial understanding of the reason for disconnect. In the issue state when unable to bringup the sslvpn s2s tunnel (do it always from the s2s client), pls check the sslvpn service state on s2s server using service -S | grep sslvpn; service should be in 'RUNNING' state. If the service is running, verify the tunnel initiation packets are reaching s2s server using tcpdump on the sslvpn port being used and from the ip address of the s2s client.

Hi !

Thank you very much for your answer.

I found these logs line on the client S2S that corresponds to the disconnection. All disconnection starts with the "Inactivity timeout" logs. What does that mean? Does it mean it can not reach the s2s server ?

Thank you very much !
