I want to filter traffic ip firewall for pppoe. While inspects is correct, I note that much traffic (pppoe) go to stop, but not observed to be blocked by any existing rule in the firewall.
I clarify that I want to do filtering on a bridge ptp, through which pass all the PPPoE connection.
I removed all firewall rules, but still follows the same behavior block some traffic.
Anyone have any idea whether it’s a bug or some other problem?
No one has implemented ip firewall for pppoe?
There is no documentation on this?
Normis, do not stain or theme idea? It is an implementation that is not to be used? (ip firewall for pppoe)
I don’t think you can painlessly drop packets inside of pppoe connection. ROS don’t rebuild tunnel, so dropping should cause retransmitting. you can only see what exactly is in PPPoE tunnel, and then shape it
I know that the ROS inspects the contents of PPPoE tunnels and even if they are rules, they work.
The issue is that with or without rules, there are connections within the tunnel to pass and others not.
For example:
Connecting to an SMTP server and / or pop3. Some servers will come and some do not.
The question is: Why?
