Extending a VLAN to Remote Office (NLAN)

We have a layer 2 connection to one of our remote offices. At our remote office we have a sonicwall appliance, it is a NSA 2400. I want to extend one of our vlan's. We have an ethernet connection from our ISP's switch running directly into our sonicwall appliance. I am wondering if anyone can tell me if it's possible to extend the vlan through the sonicwall appliance and if so, how would I do that? Will I have to install another switch and place it between our ISP's switch and the sonicwall in order to accomplish this? Make an ethernet connection from the newly installed switch directly into a part on our procurve and tag the vlan that way? It would be really cool if I could accomplish this without having to add another switch. Feedback is appreciated!

Sonicwall's appliance did not support the method I wanted to use.

Only if you ISP does QinQ will you be able to extend your vlan(s) across their network. They will need to encapsulate your vlan tags with one of their vlans.

I am not sure what you want to accomplish, a diagram might be useful.
