gui killswitch kills when on even if vpn tun is up.

[msc]

I have a single device/Source IP being routed through the OpenVPN, which is up at all times.

If I turn on the killswitch "Block routed clients if tunnel goes down" the device is blocked, although it shows up as a router client. If I turn off the killswitch, the connection to the VPN goes through. Where should I start?

With 'Block routed clients if tunnel goes down=YES'

e.g. VPN Client 1 connection is DOWN

ip route show table 111
<snip>
prohibit default

When the VPN Client 1 connection is UP, the 'prohibit default' statement is replaced by a valid 'dev tun1x' statement

ip route show table 111
<snip>
default via xxx.xxx.xxx.xxx dev tun11

So either the RPDB table for the routed device is incorrect, or the routed client is referencing the wrong RPDB table.
