Q-in-Q s-tag

  • Question on qinq.  Our ISP will be implementing q-in-q for our point to point connection, they said we just need to trunk our WAN port and their equipment will be doing the s-tags for our vlans.  So my question is, the parent tag in the Pfsense menu is the same as the s-tag our ISP is talking about, and will I need to enter the ISP's s-tag ID in PFSense for the Q-in-Q interface to work properly?
