I'm pulling my hair out here. I've tryed simply untagging and disabling vlan functionality, then reassigning to the actual device e.g. eth1.2 > eth1 ;
eth0.1 > eth0
No dice. Suggestions?
I've defaulted to default to start fresh.

What do you gain by not using vlan tags internally?
I doubt you can completely disable the internal vlan switch but I guess you should be able to change the cpu ports to untagged by changing 5t to 5u and 6t to 6u, and use eth0 and eth1 without vlan.
According to this Tech Data the switch and wan port are truly independent devices. The layout is traversed for my actual setup ootb for whatever reason. Maybe the diagram is wrong? I do understand the use of a "general-due-no-harm" setup for openwrt, but this is not necessary for this unit. The main idea behind it is many packages such as ethool, don't recognize virtual devices to ascertain direct changes or stats.
There is one switch chip with 7 ports. Five of them are the Ethernet ports on the case and two are connected to the CPU as eth0 and eth1. It is necessary to set up VLANs in the switch to independently switch one CPU port to the "WAN" ethernet and the other one to the four "LAN"s.
You could make ports 5 and 6 untagged on their respective VLANs then use untagged eth1 and eth0 going into the switch. There would still be two VLANs in the switch, but invisible to users.
It is more flexible though to leave at least one of the CPU ports tagged because then you can add more VLANs just by adding an additional tag.
Right, and also
connection to CPU eth1: port 5
connection to CPU eth0: port 6
The switch is a separate chip in the router with wires to the CPU chip. These switch ports work logically just like Ethernet ports though the type of wiring is different.
