The traffic to the Wireshark box is IPv4, no VLAN. I'm installing Wireshark on another, non-virtual box today to compare.

So that's probably a (virtual) Ethernet adapter.

In Wireshark or TShark, in the packet detail pane, there will be an
"802.1Q Virtual LAN" entry below "Ethernet II" and above "Internet
Protocol" for a packet with a VLAN header. (Or maybe more than one
"802.1Q Virtual LAN" header for a VLAN inside a VLAN, etc., but that's
probably rarer.)
(Also, this is TCP over IPv4, not TCP over IPv6, right?)
