General • Re: Switch ACL to restrict IP usage

I finally got it working. After fiddeling around it works when I add a rule at the top to allow all traffic on the customer port. After this rule I can add rules to allow the customer IP, and at the bottom a general drop rule. I also had to add mac-protocol=ip.

When the customer changes to another IP it gets blocked. Only the customer IP 10.153.4.2 is working.

This is the solution.
Code:
/interface ethernet switch ruleadd ports=ether2 switch=switch1 comment="Allow all customer port ether2"add ports=ether2 switch=switch1 mac-protocol=ip dst-address=10.153.4.2/32 comment="Allow customer IP"add ports=ether2 switch=switch1 mac-protocol=ip new-dst-ports="" comment="Drop all IP"

I figured that the rules only apply in incoming ports so I only needed the allow rule for the customer source address. The rule with customer destionation address was unnecessary.
this stopped working when upgrading to version 7.17.2, in 7.16 it worked fine.
