750 as a switch

I’m trying to connect a Mikrotik as a transparent bridge to an existing router that passes out dhcp. How can I do this and use all 5 ports?

I’m having a heck of a time finding the answer. I would think that this is simple enough to do. The problem that I can see is that if I disable DHCP on the Mikrotik I would love the ability to access it using its IP address (192.168.88.1). So that would mean that I need to set up a new static IP for it? I tried adding a bridge and putting the other ports into it, but ports 3-5 are slaved to port 2, so I can’t add them to the bridge without disassociating them. Then there’s the issue with the NAT being turned on, and the firewall, etc. It’s turning out to be more difficult to run the 750 as a plain switch without the router smarts enabled.

Step 1: Reset the router and remove the default config
Step 2: MAC Telent into the router using Winbox and add a new Bridge
Step 3: Add all 5 ports to the new bridge
Step 4: Add the IP address 192.168.88.1/24 to the bridge interface

At that point you are pretty much all done and it will work as you are requesting, but you may also want to add a gateway, set the username & password, set the clock, ect.

If you want it just as switch with ip for management, make a bridge on it with ether1 and ether2 members. Other ports are already included as switch group of ether2. Give ip on bridge or enable DHCP client on it. It will get address from running DHCP server. And that’s it.
Switch off firewall and connection tracking to speed up the transfers.

@jarda, thank you, but it’s still not working. I could no longer get outside the 750 when I made the changes you listed.
I disabled DHCP server on ether2-master-local
I had DHCP client on both bridge1 and ether1-gateway (even tried disabling the client on ether1-gateway, but no luck).
Addresses still lists 192.168.88.1 on ether2-master-local. Do I still need this? Or will I be able to get into the router config using the bridge1 IP given by the master DHCP server?
Anything else I might be missing?

Did you try to reset it? It will take less than 10 minutes to reset it and configure it?

@rickfrey: i did reset it to factory defaults. It’s working as before now, but I’m back to step one. Any suggestions for how to configure it?

Why don’t you un-slave the ports and put them in a bridge.

Putting all ports into bridge is not smart in terms of throughput as all traffic will go to and from cpu via only one line. According to what I read I have doubts if you would like to use it just a pure switch or if you want to use it also as a router. Do you have other router that plays it’s role? If so, remove config not loading defaults and try again what I wrote.
