VLAN setup and isolate it from LAN

[Guest]

New to Endian. I have been using ClearOS and Mikrotik.
I'm setting up Endian Community in my x86 PC which has 2 NICs. So, one eth0 is setup for WAN/external and other eth1 is my LAN port. I went thru the default installation and I have a working router with just LAN.

I want to set up a VLAN for my IOT and isolate it from LAN access. Doesn't matter if LAN has access to VLAN or not.

When I tried to create the VLAN I lost access.
Any help with a quick and simple steps to accomplish this is appreciated.

LAN:192.168.4.0/24
VLAN:10.0.20.0/24
Unifi 8-port switch: Tagged and untagged traffic ( it's already setup and working).

I am sadden, 590 views and no taker. I really wanted to try this out but could not figure out the proper IOT VLAN setup with firewall rules.
