Default behaviour on pfSense is to cycle all services if any configured gateways go offline, this can include VPN's and tunnels not just broadband connectivity.

This can cause problems e.g. if your pfSense is hosting LAN services such as a NTP server or UPS daemon. Consider a scenario e.g. if you have a power cut, your WAN goes offline, pfSense then puts services into a cycle loop, which in turn drops connectivity to the UPS daemon so client machines are unaware of power status and battery level which might prevent automated safe shutdown/hibernation.

This patch changes the behaviour so services will only get cycled if a external non OpenVPN interface comes back online with a different IP address, if its a cycle keeping the existing IP, then it will not cycle all services.

This is the IPv4 version of the patch, there is also a IPv6 version.
