wysiwiger said: "Full Access" is a little tricky to see, but make double-sure that it's turned on. The other problem (I've discovered) is that a firewall or router may not be passing UDP packets or the particular port for UDP (4365) may be blocked.

Hmmm.. funny you should say that - I had an email from my Vigor 2820N router the other day telling me that my pogoplug was trying to DDOS me:

2011/03/08 12:12:56 -- [DOS][Block][udp_flood, timeout=10][192.168.1.12:32771->38.122.2.46:4365][UDP][HLen=20, TLen=1442]
2011/03/08 18:55:33 -- [DOS][Block][udp_flood, timeout=10][192.168.1.12:32771->38.122.2.46:4365][UDP][HLen=20, TLen=1442]

It may be that I have revisit my router settings and allow for this false positive. Incidentally, is there a list of port numbers and protocols that the plug uses? It may make setting it up properly a bit easier..

PS .. I tried this on the router which lets me telnet in locally - will give it another try and report back:

> dos -d ATTACK_F udpflood
udpflood is disabled!
