Hi,

I guess this is related - the branch in question is triggered by
is_on_link(), so maybe in Antonio's case the tap adapter is set to
0.0.0.0 - or it actually tried to install a route related to
redirect-gateway.

Are you connecting to your VPN server over IPv6 or IPv4?  You already
spotted one weirdness with "redirect-gateway !ipv4" which still seems
to setup "something" in the route_list - so maybe it's related to that,
but needs "VPN over IPv4" to trigger.

In other words, no idea - hoping for a log from Antonio that shows the=20
"route.exe ..." call with "IF <ifindex>" so we can see what openvpn
tried to do :-)
