tunnel stops working after eth link looses sync for a mintue

Post by pappyN4 » Tue Jul 27, 2021 6:13 pm

Hi

I have a pi connected to to my router. When the router needs a reboot every so often data stops flowing through VPN connection on the pi. The only way to get it come back is to "service openvpn stop" to get traffic back to my ISP, then "start" to bring it back.

For testing, I added in a switch; so the order is MODEM--ROUTER--SWITCH--PI.

If the modem or router is rebooted. The pi maintains the tun0 / IP address and once internet is restored the VPN is functional.

When rebooting the switch or pulling the cable from eth0 on the pi this is no longer the case. tun0/ IP is preserved but all TX packets get dropped. Openvpn service status is running. ifconfig adapters are unchanged except for eth0 loosing "running" status and ip address while its disconnected. Once eth0 is back up, i can ping my gateway and other devices on the LAN. However the browser fails "DNS_PROBE_FINISHED_NO_INTERNET". Trying to ping a website fails. Pinging the ip address directly also fails. I relaxed the firewall rules incase i was too zealous in blocking but no luck.

I noticed that in the failed state the routing table was missing VPN GATEWAY MASK eth0 IP's compared to when it was working. Manually adding it back to test did not solve. Restarting the networking service also failed to do anything.

/etc/resolve.conf DNS IPs stay the same while connected to the VPN and after if enters the failed state when eth0 is pulled. The DNSs work either on the VPN or going through the ISP so i dont think it would be that.

The only way i found to get it working is to log in to the pi and stop the openvpn service, then start it.

There is an openvpn script thats runs in /etc/network/if-down.d and if-up.d when eth0 is turned off/on, but in this case its just the link that gets disconnected so it doesnt get triggered. I suppose i could do a workaround and run something to listen if the link goes off and trigger those same scripts from that...


Anyone have ideas on whats going on?

And your openvpn log file ? Please use --verb 4

Also, is it your server ?

Not my server. I dont have any access to server conf files.

Fresh reboot at 12:31, unplugged link @12:31:33, reconnect a few seconds later, stop/stop openvpn service @ 12:32 to regain connectivity to vpn
