Not that I'm aware of. It's usually AntiSpam because that's the
application that makes the most frequent use of the network. But I've
also seen it happen when DDNSC was updating and at least once on an
incoming http connection.

No. I recently bought a new Netgear router to replace the aging Draytek
and that hasn't changed anything either.

Only the default RISC OS stuff (check with inetstat -a to see what I
mean). SunFish/MoonFish appear to keep both UDP and TCP open on port
2049, but those are limited to the LAN.
