As you can see in the attached image, I am using the OPTION A scheme and it is working properly.
But I am asking you if OPTION B would be possible to save me the switch.
Now, using the mikrotik hap lite in default router mode, the eth1 port has external ip (192.168.1.3), and the rest of the ports are acting as a switch for the internal LAN (Red).
I am interested in using the mikrotik hap lite in router mode through port eth1, but I would like to use eth2 for the external network (Blue) and, eth3 and eth4 continue to be part of the internal network (Red).
Could that be possible?
Sure thing. Before doing anything else, create backup fetch file off device (so you can revert to current config in case something goes wrong). Also get winbox (if you don’t have it already) for the same reason (it can connect to MT device even if IP setup is FUBAR).
The most straight-forward way (but not the most performant one) is to create another bridge (named e.g. bridge-WAN), then move ether2 from current bridge to new bridge. Also add bridge-WAN to interface list called WAN. And move IP settings from ether1 to bridge-WAN (e.g. statically configured IP address 192.168.1.3/24). The last step would be to add ether1 to the bridge-WAN (as port).
