openvpn tunnel networks and "second network address will be assigned"
text for Tunnel Networks says "The second network address will be assigned".
It uses openvpn_get_interface_ip() which uses gen_subnetv4()
and then ip_after(). This misleadiing as it could be considered
that the first address is the address returned by gen_subnetv4()
so really the "third" netwok address will be assigned by some
Some say the first is the "network address" but that is the
terminology used here and the second is the "first IP".
My recommendation is simply to clarify the help text.
This may be needed for IPV6 and the other openvpn pages too.
