Hello friends
I have some MikroTik Access point they provide a bridged PPPoE Server .
I want to Limit communication to just PPPoE Connections , clients just connect to my accesspoint via PPPoE Protocol and drop all other protocols .
how can i do this ? for example drop all other procotols on ether 2

Hi. The solution is simple. You have to put three rules into Interface/Bridge/Filters :

add action=accept chain=forward comment=“” disabled=no mac-protocol=pppoe-discovery
add action=accept chain=forward comment=“” disabled=no mac-protocol=pppoe
add action=drop chain=forward comment=“” disabled=no

This will allow only pppoe connections to pass through bridge.

dont forget to give karma…

Thanks krajnalic
what I must to do if I want to access 192.168.20.0/24 with ICMP Protocol ?
I’m now using below rules but I can’t access to bridged devices with ICMP Ping :

/interface bridge filter
add action=accept chain=forward disabled=no mac-protocol=pppoe
add action=accept chain=forward disabled=no mac-protocol=pppoe-discovery
add action=accept chain=forward disabled=no ip-protocol=icmp mac-protocol=ip
add action=drop chain=forward comment="DROP Communication" disabled=no

where’s problem ?

you can add out-interface=ether2 in those rules
