Bridge Nat for this setup?

RouterOS General
1

Using a 750up I want to use one connection coming into eth1 to deliver 2 public IP’s to separate customers. One will be NAT’d on eth2 while the other gets an IP directly on eth3.
Getting the communications between eth1 and eth3 is no sweat with a bridge but how or should I use Bridge NAT for the customer on eth2?

Thanks

Assign your private LAN IP to your ether2 interface.

Assign a public IP to your bridge (the one with ether1 and ether3 in it). If you’re using a static IP, you need to configure a default route as well.

Then packets leaving the ether2 network will know to be routed out the bridge.

Thanks for responding Van9018
I am planning on assigning 2 publics to the device then routing one to eth2 and the other to the customer on eth3. Any special approach you would take to that setup?

No special approach. Maybe add firewall rules to prevent customers from trying to log into the Mikrotik. With default config, I think ether1 is the only one that doesn’t allow logging into the Mikrotik.
