Dear Teltonika team,
see still open case in old forum:
Failover is working fine and clients following the Internet-Connection/WAN when failover happens.
BUT, if ONLY Internet stops on an WAN-interface and interface failovers to the next interface as usual the Client-connection is still hanging on old WAN-interface that does no more provide internet.
So, Client-Connection-Flush seems NOT working, your Connection-Flush procedure does NOT recognize the internet-drop on that WAN-interface, DESPITE failover is working fine!
That’s a bug.
You could simply reproduce:
OK : Just unplug WAN-cable on router, then failover happens, then Client/Handy re-connects to new WAN (e.g. mob1sa1) or so). Fine.
NOK : Just stop Internet on WAN-cable on router, then failover happens, then Client/Handy should re-connect to new WAN (e.g. mob1sa1) or so) - but Client still hangs on old internet-less connection.
