Good day:

I need to create a script that clears all firewall connections if it detects a change in ISP. The problem we have is that when failover occurs, VoIP phones connection hang. This occurs in a place where internet is very unstable.

This should clear all connection, but not sure how to trigger it:
Did find a shorter version:
This may be used to clear only the sip sections (not tested):

This

Code: Select all

/ip firewall connection remove [find]

I have this exact command in my netwatch when it checks if the Primary ISP's DNS server is there AFTER RECURSIVE ROUTING.

So it CLEARS all connections whether flipping too or away from the Primary ISP.
