Gateway alarm always trigger IPsec restart
There are several issues:
1) '/etc/rc.gateway_alarm' trigger '/etc/rc.newipsecdns' which generate an invalid log message:
IPSEC: One or more IPsec tunnel endpoints has changed its IP. Refreshing.
- which can confuse users.
This message is only true if IPsec remote-gateway == FQDN and filterdns updates it's IP.
2) It is not necessary to restart IPsec if an alarm is triggered for the Gateway that doesn't affect IPsec connections. It should be more flexible, like '/etc/rc.openvpn'.
3) It's better to create '/etc/rc.ipsec' in the same way as '/etc/rc.openvpn' and use '/etc/rc.newipsecdns' only for filterdns updates.
