OpenVPN server connection and tunneling back out
-
@davidstoll
The OpenVPN versions are mentioned in the clients log files. -
Actually, there is more than one change in the config file. Anywhere there is a #, I had to remove it or, in that a couple cases, make a correction.
In any case, I just searched through the log file on my android and there was no mention of the version or 2.4 or 2.5.
In the Windows client, the log file shows 2.4.4.

Sorry, deleted the log file because there was something in there that I didn't edit....anyway, here it is again...

If I uncomment out the lines from my auto generated config and remove my replacement items, I get the following short info from the log...
Options error: Unrecognized option or missing or extra parameter(s) in pfSense-TCP4-config.ovpn:4: data-ciphers (2.4.3)
Use --help for more information. -

Since you're running an 2.4.x client, check "Legacy Client" in the client export utility and export a new config file. -
@viragomann I don't have any options. I can only click on the OS that I am trying to export for. Is there a better export plugin maybe? I'm using "Openvpn-client-export v1.6_4, which seems to be the latest as far as I can tell.

Try this one:
-
Ok, thanks. I did that and it only gave me one warning about password caching, so that did help with the config compatibility.
However, every 3 hours it disconnects.

@davidstoll Any other suggestions? I would really appreciate it. I think we have made it a little better, but it just doesn't wan to stay connected and it disconnects on a scheduled basis (not randomly).

I tried UDP, but it won't connect...

@davidstoll
Looks like the server is not responding due to whatever reason.Use packet capture on pfSense to check if the client packets are arriving on the WAN.
-
@viragomann They definitely are....up until it disconnects because it's working just fine other than the disconnect.
