VLAN issue with 520G-24TC-K9

[trevorseward]

I went from a Dell web-managed switch to a 520G.  I have a workstation with Hyper-V, this workstation has 2 physical NICs plugged into a Dell unmanaged switch, which is subsequently plugged into the 520G.  One physical NIC is dedicated to Hyper-V, the other is for standard workstation traffic.

My Hyper-V VMs do not have network access unless I enable VLAN tagging (ID of 1).  Once enabled, I can ping the router, but I cannot ping other machines on the network (machines either plugged into the same Dell unmanaged switch or servers directly plugged into the 520G).  Any ideas?  I thought that network access would work if I just left everything 'untagged'.

Every port on the switch is configured with VLAN ID 1.
