Hey，Senatordan, Which kind of VPN do you use in the issue? PPTP Site to Site or L2TP Site to Site? I need t know that to see if I can help you.

Hey, I suggest you can contact the Technical Support of TP-Link directly.

What do you mean" I've turned off DHCP server in the load balancer and that didn't seem to work"? The Clients still can get IPs from it?

I have noticed that too, did this function of priority have influences on your needs? What do you really want?

Hi dude, maybe you can try this: VLAN 1: default port 1-24 untagged VNAN 2: (another switch)Port 2 tagged; port 4 untagged(Internet) VLAN 8: (for your purpose): Port 4(Internet); port 12(wireless...

I'm afraid you cannot do that, because the TL-SG108E support 9V input Voltage which means 12V is higher than that.
