Remove all firewall settings before import

RouterOS Scripting
1

Hi,
I want to sync my firewall settings from one VRRP router to another. Therefore I’m exporting the rules with

/ip firewall export file=firewallrules

. But before import on the second router I have to wipe out all firewall settings. How could I do this?

Commands in "Building Your First Firewall" conflict with VPN ?

/ip firewall filter remove [find]
/ip firewall nat remove [find]
/ip firewall raw remove [find]
/ip firewall mangle remove [find]
/ip firewall address-list remove [find]
/ip firewall layer7-protocol remove [find]
/ip firewall connection remove [find]

Thanks! But sorry, I’ve fogot to mention that I’ve already tried this one:

/ip firewall filter remove [find]

But it gives the error

failure: cannot remove builtin

and does not remove any rules.

I guess this is because of rule 0, which is a builtin rule for fasttrack.

This should work

/ip firewall filter remove [find dynamic=no]

Thanks, that one works!

I use find comment = “defcon” on new routers.

Will have to try that dynamic no at some point on a running router.

Thing is… I import my new rules THEN delete the old ones.
