Sharing an uplink (is it possible?)

RouterOS Beginner Basics
1

Good Day!

I am extremely new to RouterOS and really routing in general so please bare with me.

I can’t seem to find anything on what i’m trying to do, so it may not be possible.

My current setup is uplink → Switch → Routerboard’s WAN interface (in this case port 1)
–>Wireless access point

What I would like to try and do is get rid of the switch in the middle.

Is there a way to use say ports 1 and 2 as switch ports AND have routeros know that that group is the WAN? I don’t want any sort of tagging on these ports. Basically i want both the routerboard and WAP be on the same network as the uplink and the rest of the port on the RB to be served by routeros.

As I said i’m sure new to this and really want to learn, this seems like it should be doable but I can’t wrap my head around this.

Thanks in advance!

Now this is easy :slight_smile:

Basically, just add a new bridge, add ether1 and ether2 as members, assign your WAN IP to the bridge and off you go.
In case you have a RB with switch chips inside, you can also just add ether2 as slave port to ether1 and assign the bementioned IP address to ether1. In this configuration, you have full wire speed on the WAN side. In this case, don’t forget to remove other ether ports from ether1 master (as they’re most likeley LAN ports then).
Then add another bridge for your LAN side.

Thank you so much!

I figured it must be possible with such a powerful device.

My next mission is the add that bridge to a vlan truck and see if I can the wan side connection down stream one switch. Wish me luck and thanks again for your help!
