Bandwidth usage question

Postby Dr-Jon » Wed May 31, 2017 2:36 pm

HI, I have an OpenVPN server on my desk that connects to 2 client machines over 3G
there is a 4G router here and 2 3G routers at the other end.
My question is as i'm paying per Gb for the data connections, How much data will the vpn tunnels use. I know the data transfered across the tunnels will be included but if there were no traffic just the tunnels how much data would these use?
Thanks

It depends on your configuration ..

See --keepalive for instance and use --dev-type tun not --dev-type tap.
