MS510TXM need some general assistance with Routing config

Hello everyone!!  

Sorry it's been so long for my reply.  I've purchased a GS108Tv3, which uses the same fw as my MS510TXM.  This way I can troubleshoot the issue from a completely isolated environment.  I am seeing the same issue, where a non-tagged device on a non-tagged VLAN cannot talk to a tagged device on a different tagged VLAN.

I have the default management VLAN on VLAN 1 on subnet 192.168.2.0.  - Management ip is .1

My untagged VLAN is 3 on subnet 192.168.3.0 - Router interface is .1

My tagged VLAN is 4 on subnet 192.168.4.0 - Router interface is .1

I have 2 laptops. 

The first one has 2 usb to ethernet adapters.  One adapter is on the (untagged) management network (address 192.168.2.10).  The other adapter is able to be set to a VLAN.  I have it configured to use tagged VLAN 4 and I can ping the gateway address of 192.168.4.1.

The other laptop has a built-in ethernet adapter.  I have it configured to talk on the non-tagged VLAN 3 with address 192.168.3.87.  I can also ping its gateway address of 192.168.3.1.

From the switch, I can see both laptops' addresses in the routing table.

I have tried various permutations of the PVID settings, but none seem to allow the 2 networks to talk to each other.  Here is the current PVID config: 

The end goal is to allow a device on the untagged 192.168.3.0 network to communicate with a device on the tagged 192.168.4.0 network.  

We can break this switch config at will!

Thanks for the help, and Happy New Year!!!
