@Gertjan said in OpenVPN - Making it more tolerant to packet loss without re-auth:
Isn't keepalive a TCP thing ?
Actually, it's an application thing and can be over TCP or UDP. IIRC, there is no keep alive function in TCP, only timeout.
Incidentally, several years ago, I tried an experiment. I was in a coffee shop and used the WiFi to set up a VPN. I noticed there was another open WiFi in the area. I was able to switch WiFi, without dropping the VPN. This is a result of using UDP to carry the VPN. So long as the other end is reachable, it doesn't care how it gets there. This is also why, with WiFi calling, you can transparently move between a WiFi and cell network connection.
BTW, that coffee shop was at the corner of Harbord and Grace in Toronto. That other WiFi's SSID was "GraceLAN". 😉
