On the topic of UPnP, does anyone have any advice on whether to use the
IUPnPNAT interface in Win32 versus going straight to the UPnP layer?
Stay as far away from IUPnPNAT as possible. This bundle of joy tends
to randomly fail perfectly valid requests with undocumented return
codes. It also depends on SSDP service, which is frequently painted
as a major security hole and therefore scares users off.
Did you skip SSDP and just send UPnP requests straight to the gateway? This
seems reasonable, given that DHCP has already done all the hard work of
locating it.
UPnP code in Hamachi does not rely on SSDP. It does its own UPnP device
discovery (via multicasted M-SEARCH) and then communicates with whatever
device that supports required functionality.
IIRC discovery portion is required, because it's the way to get URL for
UPnP/SOAP calls on the device. Merely assuming that DHCP server is the
device does not give you much.
