Good morning, I have a GS308T that I am trying to configure and I am having difficulty. I need one physical port (port 1) to connect to my router as the trunk / access port for all traffic to the I...

The PVID config option might exist just so they can say it exists, not because they intend it to be used.
Considering the presence (and requirement) to not forget to configure the PVID to send the untgged ingress to the correct VLAN is probably the #1 VLAN switch support issue .... figure.

That switch has no layer-3 routing ability so you can't do what you want the way you want to do it.
There's a right way and a wrong way to do this IMHO
The wrong way is to put everything into 1 VLAN then use a series of MAC address ACL's on the switch to prevent things from taking to each other but allow them to talk to the Internet port. That's what you are trying to do but you are misunderstanding what a VLAN is and how it works which is why you are failing. I also assume your "Internet connection" is a translated private address from a router.
The right way is to replace your Internet router that is doing the translation with one that can create multiple VLANs as well as do the network address translation between the Internet and multiple internal network subnets. The router would supply all the VLANS on the trunking port to the switch as well as run ACL's that would block the machines on the different VLANs from talking to each other.
OR just replace the switch with one with layer 3 routing capabilities and address translation capabilities but that's really high end $witch feature$ if you get my drift...
