Forwarding a packet to different destination on bridge

RouterOS Beginner Basics

Hey,

sorry for this beginner question.

All happens on a bridged interface.
A NTP request (123/UDP) is sent from 192.168.199.33 (wlan2) to 192.168.199.1 (eth). However, I want to have the packet forwarded to 192.168.199.2 (eth).

I have a very similar dst-nat rule that works if I am sending the request from another interface (i.e. not on this bridge), but inside the bridge it does not work despite the NAT rule counter goes up:

add action=dst-nat chain=dstnat comment="NTP Request (UDP 123)" \
    dst-address=192.168.199.1 dst-port=123 log=yes log-prefix=nattest protocol=\
    udp src-address=192.168.199.33 to-addresses=192.168.199.2

If this is handled on L2 only, why is the IP NAT counter incrementing? Is there a way to redirect the packet inside a bridge based on IP?

Thanks,
Daniel

You can do what you ask with switch rules…if your switch chip supports these features, a matter of speculation since you haven’t identified it.
