Hi, I've been using openvpn with at tunnelblick client for about a decade and I've had the server running in an OpenVZ container with Ubuntu 14.04.5 LTS for the last couple of years. I use it constantly every day and it's been working.
This morning bright and early I replaced my old linux router with a Sonicwall 4600 and then OpenVPN stopped working right. Symptom wise it looks like the new firewall is just coincidental because I can see tunnel traffic coming into the server on UDP 1194 and a little on 500 but not much comes and goes in and out of the tun interface. I did make sure that the firewall was allowing fragmented packets on the access rules and checked that the MTU was ok. Server side the tun ip at 10.8.0.1 is pingable but nothing else in the tunnel. Client side nothing is pingable and the Mac gets hung trying to read it's routing table. But tunnleblick thinks it's connected successfully. When I try to disconnect the client Tunnleblick says it's successful but then whatever has happened causes the tun interface on the server to stop answering all together and the container has to be rebooted for it to try again. I updated the client and server to see if the problems went away but no luck. The same symptoms persist no matter what. The Nat rule is in right and the right switch is in my vz config file. Nothing changed between last night and this morning but the firewall in between and that seem so be passing the traffic like it's supposed to. I'll try windows and Linux clients tomorrow but does anybody have any debugging suggestions that I haven't thought of?
