    Hi,

    I have a couple of access-ports in a vlan (on an EX3300 running 12.3R7.7, one particular port should only allow traffic from specific ip-addresses.

    I thought that would be straight forward so i configured it like this:

    > show configuration firewall family ethernet-switching filter server-oob
    term oob-access {
        from {
            source-address {
                10.146.77.15/32;
                172.16.18.44/32;
            }
        }
        then accept;
    }
     
    > show configuration interfaces ge-1/0/26
    description "Server OOB";
    unit 0 {
        family ethernet-switching {
            port-mode access;
            vlan {
                members s-oob;
            }
            filter {
                output server-oob;
            }
        }
    }

    So the servers OOB port is connected to ge-1/0/26 and the addresses that should be allowed access to that interface is coming from other vlans.

    When i commit this all traffic stops to that interface, why is that? And why is the traffic from the specific addresses not allowed?

     

    If i remove the filter on the port, traffic flows fine.

     

    Kind Regards
