Description

The script /usr/local/sbin/ovpn-linkup has en error where network mask is returned as a gateway when no gateway provided by the server:

if [ "${dev_type}" = "tun" ]; then
    if [ "" != "$route_vpn_gateway" ]; then
        /bin/echo $route_vpn_gateway > /tmp/$1_router
    else
        /bin/echo $5 > /tmp/$1_router
    fi
fi

See "ovpn log.txt" attachment. 5th argument passed to the script is a network mask. The script should use interface IP (the 4th argument) as it's gateway ... like in GRE tunnel configuration.
