i have 2 router boards CCR1016-12G, each router board is assigned with a real IP , when i go to the first board and try to torch the interface with the real IP i find the IP address assigned on the second board, i tried to apply a filter rule:
XXX.XXX.XXX.XXX is the IP address on the second board
i can see traffic going on this rule but i can also see the "XXX.XXX.XXX.XXX" IP address on the torch
can someone please help

That is a forward rule. If you are using torch from one of the routers, and there is traffic from that router, then that would be an output rule.

If i go to RB1 and torch Ether3 i can see the IP address that i putted on RB2
the following pictures will help understanding
