Is there a way to flush the firewall rules using a script?
I noticed that if I make big changes to the firewall script from the export option and then re-import it, All the rules get added, so now each chain has double the rules.
If there was to add a command to the top of the script to remove all the rules, so when importing they wouldn’t double up that would be great.
Anyone know how I might go about doing this. This is on 2.9
Thanks,

A work around I see would be to add into the script
/ip firewall filter
print input
remove $rule numbers go here.
That seems crude, is there a way to say remove all in input chain with out having to print, and then designate each rule?

Something along the lines of
/ip firewall filter remove [/ip firewall filter find chain=input]
Just quickly typed from memory - please test first before blaming me for the loss of all your rules in other chains 
Cmit,
That did the trick. I don’t understand why this wouldn’t work.
/ip firewall filter remove chain=input
Anyway, this works just as well. Thanks for the help.

If you find some spare minutes, read the scripting section from the manual thoroughly.
The scripting features in RouterOS can save you tons of work often…
Ya I haven’t had the chance yet, but this is definately the next thing I am diving into. I am starting to realize the power of scripts!!!
this should aready be implemented in the os : it already exists in iptables ie : routeros sucks. /rant
