I have a Balance 20 router with latest firmware. I’m testing what I thought would be a very simplified VLAN configuration to isolate a set of network devices from the rest of my LAN, and it’s not working as expected. I posted earlier asking for general advice, and got some great help (see Need some hand-holding to create separate LAN). This was my first step towards implementation. My simplified topology consists of the Peplink Balance 20 with LAN port 1 connected to my switch (and the rest of my network), and LAN port 4 setup as VLAN 4. I’m testing it by directly connecting my laptop to LAN port 4, as such:

In my router, I have two LANs defined – the default “Untagged LAN” with VLAN = “None”, defined as 10.88.88.1/24, and the new VLAN, “ExtNet4” with VLAN = 4, and network defined as 10.44.44.4/24.
Both networks have DHCP server enabled, and Inter-VLAN Routing disabled. I have no static routes defined. Under Port settings, I have LAN ports 1-3 set to Port Type = Trunk and VLAN = Any, and I have LAN port 4 set too Port Type = Trunk, and VLAN = ExtNet4.
I expected that this would let me plug my laptop into LAN port 4 on the router, and I’d be issued a DHCP-assigned IP of 10.44.44.10 (first address in my DCHP range), and I’d be able to route out to the internet without a hitch, but not be able to see or route to anything else on my LAN.
What I actually got, though is nothing. I do not get any DHCP address assigned. I cannot even ping 10.44.44.4 when connected to LAN port 4. Connecting my laptop to any other port gives me a 10.88.88.xxx IP address, and I can see everything. Also, if I change Port settings for LAN port 4 to VLAN = Any, then my laptop gets a 10.88.88.xxx IP address and I can see everything.
I’m sure I’m must misunderstanding something, or missing some other key setting. I’d be grateful for some advice!
