Description

When using dual-stack on a WAN, and the IPv6 gateway goes down, both IPv4 and IPv6 services on the WAN are restarted.
This causes an unnecessary disruption in the IPv4 services that may not have had a failure.

It can also lead to a loop with an assigned OpenVPN interface:

apinger sees IPv6 gateway down, restarts services on wan
check_reload_status restarts OpenVPN
OpenVPN restarts, which causes an interface event for the assigned interface (e.g. ovpns1)
rc.newwanip restarts some things, including apinger

apinger sees IPv6 gateway down, restarts services on wan
check_reload_status restarts OpenVPN
[loop, loop, loop...]
