script to make firewall rules

RouterOS Scripting
1

Hi

can someone help with a script that can isolate my 13 ethernet ports from each other in a mesh topology like?

/ip firewall filter
add action=drop chain=forward in-bridge-port=
ether2 out-bridge-port=ether1

thats 1 rule, to make them for 13 ports it will probably be around 156 rules :open_mouth:

So is it possible to make a script for this?

Use split horizon bridging. You will achieve the same result, no firewall, much faster, much less config.

Hi. This is not working, it can ping right through it

4 ports bridged to a bridge called Birdge1, I played around on the 4 ports and changed the Horizon value on the bridge, it doesn’t do anything as expected or am I missing something?

ok problem fixed, hehe, I’m a idiot :stuck_out_tongue: ..I used common sense and the forward rule on bridge
