Mikrotik pppoe Domru + telephony pppoe Domru 1 wan?

Question

Mikrotik

Hello.
We have:
a) Cable from Domru (pppoe, internet) coming to port eth1 Mikrotik (hap ac2).
b) The second separate cable coming from Domru to the VoiP gateway (the gateway also raises its pppoe, phone connection).
Needed:
Leave one cable, and let the gateway through Mikrotik.

When there was Keenetic, there were no problems. There is a pppoe pass through feature. I activated it and everything worked. And what about Mikrotik?

Answer 1

There is the same function.
You need (as an option) to throw the port to the gateway bodies into the bridge with the Mikrotik van interface

Answer 2

Try this: combine two interfaces into a bridge - to which the provider's cable comes, and which goes from the microt to the voip gateway; on the micro, you establish a pppoe connection from the bridge, on the gateway as usual.
UPD: but, sorry, I didn’t see that in the comments to the next answer they had already figured out everything.
