VLAN Basics

[biopepe]

Hi,

I'm new to OPNsense or any other firewall.

I have a PC with 6 RJ-45 ports. I've configured the interfaces this way:
Port1: WAN
Port2: LAN1
Port3: LAN2
Port4: LAN3
Port5: LAN4
Port6: Not configured

LAN1 to LAN4 are setup as bridge.
I want to connect a basic Wifi AP to give guest access to Internet. Devices connected through this port must not have access to LAN bridge. I've followed the following guide (without the Captive Portal steps) and with the firewall rules everything is working as I wanted:
https://github.com/opnsense/docs/blob/master/source/manual/how-tos/guestnet.rst

The questions are: Is the lan bridge enough protected with this configuration? Is possible to setup a VLAN for the interface on Port6? Would it be better to setup a VLAN for guest access?

Thank you.

im no expert but if possible for you to setit up as a separate LAN then that would be fine.

Thank you. I won't use VLANs this time.
