ROS Firewall filter (iptables based) works on a first match basis; so all you need is to add a firewall rule with action=accept for such ethernet before your blocking rules.

i think there is something i am not getting..it will be kind enough if you walked me through..im trying to exempt port 10.50.50.0/24 from all my firewalls rules..see attached pdf [attachment=0]rules.pdf[/attachment]

add these rules, they’ll be added as the first ones:

/ip firewall filter
add action=accept chain=input src-address=10.50.50.0/24 place-before=0
add action=accept chain=forward src-address=10.50.50.0/24 place-before=0

This instructs the firewall to leave them alone, they match the first rule, so no further rules will be applied for 10.50.50.0/24 on input and forward chains.
