I have a RB493. It's running ROS 5.5.
I want to block all access from WinBox clients on 'ether4', unfortunately I don't seem to be able to do so.
If I create the following three rules:
Code: Select all
/ip firewall filter
add action=drop chain=input disabled=no in-interface=ether4
add action=drop chain=output disabled=no out-interface=ether4
add action=drop chain=forward disabled=no
The worrying thing is that the firewall appears to be working (input chain rule count incrementing), but it clearly isn't. What other kinds of traffic can bypass the filter?
