A posting on an unrelated subject reminded me about something: I recently upgraded my broadband service from ADSL (copper) to fibre, and a new router was supplied. I've since discovered that the router (a Sagemcomm F@st 5355), get this, *does not pass outbound UDP packets*! (And I cannot configure its firewall to do so.) So things like NTP and TRACEROUTE etc are stuffed... So, my question is: is UDP used anywhere in the update process? -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer."
