Is this a known issues of AR750S's firmware?

In firmware version 3.104. If the “VPN Policies”, “Use VPN for all processes on the router” and “Use VPN for guest network” are on and have these options “Domain/IP” and “Do not use VPN for the followings” selected.

It’s impossible to switch profile in the OpenVPN Client, the router just keeps trying to reconnect.

And toggle the Physical OpenVPN switch from ON to OFF the internet connection drops.

Try out this firmware, might resolve your issue: GL-AR750S-Ext VPN Policies work but kill internet - #12 by corefocus
