Firewall filter EX4600

Hi,

I want to create some firewall filters on EX4600.

I just want network 192.168.11.0/24 talk only to 192.168.12.0/24 and 192.168.12.0/24 only to 192.168.11.0/24.

I created this rules :

root@SD-TST-C012-1# show firewall family inet filter ACL_IN
term T1 {
    from {
        source-address {
            192.168.11.0/24;
        }
        destination-address {
            192.168.12.0/24;
        }
    }
    then accept;
}


root@SD-TST-C012-1# show firewall family inet filter ACL_OUT
term T1 {
    from {
        source-address {
            192.168.12.0/24;
        }
        destination-address {
            192.168.11.0/24;
        }
    }
    then accept;
}

I applied this configuration on my IRB interface :

root@SD-TST-C012-1# show interfaces irb.3082 family inet
filter {
    input ACL_IN;
    output ACL_OUT;
}
address 192.168.11.1/24 {
    vrrp-group 11 {
        virtual-address 192.168.11.3;
        priority 200;
        accept-data;
    }
}
root@SD-TST-C012-2# show interfaces irb.3082 family inet
filter {
    input ACL_IN;
    output ACL_OUT;
}
address 192.168.11.2/24 {
    vrrp-group 11 {
        virtual-address 192.168.11.3;
        priority 100;
        accept-data;
    }
}

My problem is nothing ping.

Do you have an idea ?

Thank you.
