Issue with Openvpn Reconnect?

killmasta93

Thanks for the reply correct only have on the computer, maybe I would need to implement the keep alive option?

Rico

Well keepalive 10 60 is the default and already set by pfSense.

hmm..so everything is good on my part? or how can i demonstrate the issue is not pfSense?

Rico

Please share your Client Config file.

Thanks for the reply i download the bundled and the ovpn is this for the client

dev tun
persist-tun

cipher AES-128-CBC
ncp-ciphers AES-128-GCM

tls-client
client
resolv-retry infinite
remote 181.xx.xx.xx 1194 udp
verify-x509-name "pfSense OpenVPN" name
auth-user-pass
pkcs12 Olympus-UDP4-1194-test.p12
tls-auth Olympus-UDP4-1194-test-tls.key 1
remote-cert-tls server

I was looking at the logs to see and got alots of this

Feb 12 13:26:29	openvpn	18543	Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #101914 ] -- see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings

Rico

Authenticate/Decrypt packet error could be the clock drifted off on one or both sides, wrong MTU or again, flaky internet connection. AGAIN the question, you have this issue with all your clients or only some?
You could also try to switch from UDP to TCP which is not recommended in general for OpenVPN, but can help with unstable connections.

Thanks for the reply, ill keep it right now UDP as for the encryption everything else is good?

Rico

Well you can‘t do much wrong with the encryption part, everything is fine as long both sides match.

While TCP for sure is not going to be as fast as UDP.. Huge advantage with it is works over proxies... And if you run it on standard 443 port.. You prob can access it from almost anywhere.. While standard port and UDP not so much..

I just run 2 instances, one on standard 1194 UDP, and than another on 443 TCP. If can not get to the UDP from where I am at - never had issue with getting to the tcp one.

killmasta93

Thanks for the reply, so recommended to run UDP better?

johnpoz

UDP should be better yeah - unless you can not get to it, then is useless ;)

Takes nothing more than some simple setup to run both. And if you configure the client settings correctly - it will first try your UDP connection, and if can not connect it will then try TCP.
