You can create different portals based on different tables from
Method. The default portal is based on the Contacts tables but you can create
portals based on Employees, Vendors or Customers.
One way of achieving what you are looking for(Without creating a new portal) is to create a
custom field that keeps track of the portal that a user should have access to
and on the OnScreenLoad of the first screen that loads in the portal use the
Show / Hide Tab link action to show or hide tab links.
Pseudo
code example:
If user portal type = US Dealers
Show Tab Link A
Show Tab Link B
Show Tab Link C
End If
If user portal type = Direct Consumers
Show Tab Link D
Show Tab Link E
End If
