Just to clarify, both VM's are on a single ESXi server on a virtual 
switch, so no network hardware is involved. It is possible to configure 
the virtual switch to be on no vlan and on a specific vlan, but in both 
cases it didn't work. I'll see if I there are more settings I can change 
on the virtual switch.
