Openvpn connecting but no traffic back.
-
I am running openvpn on my pfsense so I can use jellyfin away from home. It was working for months but now has stopped working. My phone is the only client it seems to connect quickly. When I take a packet capture at the firewall, I see a packet come from the phone, the server responds with a 302, the phone makes a new GET then the server sends a bunch of data and the phone resends the syn packet. Jellyfin works fine when I am on the network. I cannot think of any changes I made before it just stopped working. I setup dynamic dns but that was working for a few weeks before it stopped. Has anybody seen anything like this?
My openvpn client is a different IP space from my LAN. I don't do any natting on the vpn. The firewall has routes for it. I can ping the phone from my jellyfin server so that works. I am at a loss. Any ideas?

When I take a packet capture on my firewall, on the ovpn1 interface, I see the traffic going back down the tunnel. So that means the traffic is making it back to my client right?

No, the only way you can be sure of what's arriving at the client is to do packet captures on the client. In your example, is the client the endpoint? Or a router? Perhaps the packets make it as far as the other router, but no further.

@jknott my android mobile is the client. I cannot find a way to do the packet capture as all the apps use a VPN to collect the packets. I changed my forwall rule and that broke it so I know it have the firewall rule right. I tried sending all traffic and I cannot get that to work. So I might have a routing issue internal on the firewall but then I would not see the traffic going back out ovpn interface.

I change my openvpn firewall rule on the WAN interface destination to "WAN address" from "this firewall (self)" . It seems that the "this firewall (self}" does not update the state table correctly, that is why I can make small call and get my 302 but not send any real data. So use the "WAN address" for the destination for the openvpn rules.
