What is an "AP Direct Tunnel" on the SZ series controllers?

Question

On the licensing page of my SZ-124 I see "AP Capacity Licenses" and "AP Direct Tunnel Licenses".

I have lots of Capacity licenses but no Direct Tunnel licenses.  Can someone describe the feature unlocked by this license?  We already tunnel a WLAN back to our SZ via the "Tunnel WLAN traffic through Ruckus GRE" option on WLAN configuration.  The Direct Tunnel license doesn't seem to be tied to this.

I tried doing a ctrl-f search of the SZ admin guide but no luck...

Thanks!

PS. SmartZone doesn't seem to be listed in the product listing of "Related Categories" at the bottom of this posting submission page.

Hello Grey_WiGuy, I have similar question regarding SoftGRE and GRE tunneling. Contents of the link you provided require active Wireless support account, which I don't have. So, please can you paste its contents here?

SoftGRE or GRE require AP tunnel license? Because I setting up GRE tunneling without having AP tunnel license.

Thanks Michael, I'll keep this in mind for the future 🙂  I'm stuck in a bubble I guess, just me and my SZ-124 😄

...and also, SmartCell Gateway is synonomous with SmartZone Greg!  I'll get that updated.
