Bridge - same port in, same port out, possible?

RouterOS General
1

Hello all,

will it possible to bridge the packets for example on in:ether1, out:ether1 ?

The case is (still) with powerline where only one powerline (or more for redundancy) will accept incoming requests from clients and is also connected to the next hop in row, so the packet gets in from clients and is getting out on the same interface.
Mikrotik doesn’t seem to forward such packets.

Possible?

Thanks,
Juergen

Please be more specific, otherwise I do not understand your question.

Sorry :slight_smile:
I try to clarify this a litle bit.

Powerline acts like a ethernet replacement. E.g.:

Mikrotik <=> [POWERLINE1] <=============> [POWERLINE2] <=> Client PC

^^^^^^^^ <=============> [POWERLINE3] <=> Mikrotik to Internet

So, see above, POWERLINE1 has a connection to POWERLINE2 and POWERLINE3 but POWERLINE2 has no connection to POWERLINE3, so i need to make some kind of routing (but without the routing for intact client mac address).
Now, the powerline has only ONE ethernet interface.

In fact - now the packets are coming from POWERLINE2, reach POWERLINE1 and should be forwarded to POWERLINE3 without modifying the clients mac address.

Possible?

I tried a eoip tunnel resulting in a loop (whyever, i didn’t find the point - the arp requests just deadlooped, even with enabled rstp). But with that i got 2 interfaces, one for incoming transfers and the second (eoip) for outgoing to the main mikrotik device. This worked, but as mentintioned before, deadlooped for some reason :frowning: However, that deadloop is now not the problem as i try to simplify things with a simple bridge…
