Vigor 2600+Teamspeak=router reboot?

[Splash]

Hokay - so for some reason whenever me and the missus both connect to a Teamspeak server (same one) at the same time our router bums out after a couple of minutes. I would expect this of a cheapo router, but this is a vigor 2600! Only seems to happen when we use Teamspeak.

I've dropped a message on the Draytek forums, buit wondered if any of you lovely ladies and gents had anything like this happen in the past? Firmware is 2.5.6_UK which is the latest version according to the website.

The strange thing is that we used to host the server on our LAN and all was fine, only since hosting it elsewhere have things gone awry...

Do you have SPI enabled? UPnP?

Those are a couple of things I can think might cause issues, though frankly I'm not in any way certain.

UPnP was, have disabled it and will test this evening. There seems to be no easy way to disable SPI when running NAT on the 2600 though
