Hi Rafael,

Thank you for the clarification. 

But given that a legacy CPE, even in the bridge mode, does not leak UPnP IGD messages in the WAN interface, I guess an upgrade is still needed to relax that?

BTW, are you aware of tests that have been conducted to confirm this behavior (I'm talking about the UPnP IGD leg)?

Thank you.

Cheers,
Med
