Im not sure that's what the OP was asking for (and not what I'd like to know!)
Having examined the user guide, and what is possible in the WiNG AP configuration, I suspect the answer is no, but:
Is it even possible to use an access point to perform dynamic updates to a service such as DynDNS / No-IP, which are intended for domestic Internet subscribers with a non-static IP address to ensure that their home IP is always resolvable from any Internet DNS server.
(This has been possible in Cisco IOS, for example, since version 12.2, I think, using the "ddns" config).
I hope I've described that properly. Thanks for looking!
