Traffic Mirroring

Hey there guys,
Is there anyway to mirror my PPPOE interface traffic to an ip in my network >?
I have a hEX S Router running the last version

The maximum you can do is to use mangle rules with action=sniff-tzsp to encapsulate any matching packets (such as those entering or exiting through a given interface) into UDP packets with a special header and send them to a pre-defined IP address and port. This only works if fasttracking is disabled, and the receiving side must be able to extract the original packet data from the TZSP encapsulation, so if the purpose is to use some Intrusion Detection System, make sure that the chosen one can handle this.
