(R80.10) CheckUp mirroring on different interfaces

Dmitriy_Chazov — Mon, 16 Jul 2018 06:01:25 GMT

Hi ChechkMates
I wanted to know how to correctly configure the solution, when we mirror the traffic of the customer from two points to 2 ports ChekPoint.

For example.
One point is the incoming Internet channel to the router (eth1) and the other is internal (eth2).

Question:
In the network topology, when we define interfaces, this is defined as the Internet eth1 (external) and eth2 (This Network) (Internal)?

Hi Dmitriy,

setup is as usual for mirror ports. Our engine will reconstruct traffic from any mirror port you add.

But remember that you might inspect traffic twice hence you get two logs for the same traffic.

Hi Thomas Werner‌,

Yes, I remember about traffic, but still they did not answer about the topology.

Hi Dmitriy,

what do you exactly refer to ?

A mirror port does not have any topology.

Thomas, I forgot to highlight the essence of the issue, see the question in the first post.

Dmitriy,

sorry I still do not understand your question.

Mirror Ports are always configured without topology. The packets simply arrive at these interfaces but do not leave via another interface. So there is no topology assignment possible. Therefore you need to set inspect policies to inspect all traffic.

Here is an example, see from 0.27, when the mirrored interface is redefined and set as "Internet (External)"
