Greetings Ed,

Yes, a NAT will protect you from Messenger Service popups, but, I think he probably had his
PC set into the DMZ of the router. That's really the only explanation, and no, firstly,
regardless what "ports" an application opens on a computer, the router will still be blocking
incoming connections. Kazaa, behind a NAT-based device, can only make outgoing connections,
nothing "incoming" (especially from something other then Kazaa), can "hitchhike" that
connection and come in -- it's not possible.

The only exception to this is Universal Plug and Play (UPnP) support in the router, which an
application can use to automatically open ports, which currently (as far as I know) the only
mainstream applications that support UPnP are Windows Messenger (*NOT* the 'Messenger
Service' popups) and MSN Messenger.

Hi Sparky,

I honestly can't explain that, but since there's so many routers, and firmware versions,
perhaps one of them is actually "supporting" the service in the router?

Regardless, it's further proof the real solution is to turn off the service.

Thanks to those who replied.
It is a Linksys Router Wireless with latest firmware. It is a Universal
Plug and Play Router with it enabled and running XP. XP has Universal Plug
and Play installed.

So, I guess he has to settle for turning off Windows Messenger Service. We
were just trying to figure out how the pop ups were coming in. I had also
thought like what you guys say that the router should have kept them out.

Thanks,
Ed.
