I *strongly* recommand NOT using the LocalAddresses like that. Every time
the property is accessed, the list is re-populated. So you have a potential
for the list to change dynamically while you are still looping through it.
That is why the example I gave you earlier was storing the returned TStrings
pointer into a separate variable so that the property is accessed only once.

You do not need to index into the Bindings like that. Add() returns the
necessary TIdSocketHandle object pointer.
with Bindings.Add do
begin
IP := GStack.LocalAddresses[i];
Log.Write(LLNormal, 'Created binding ' + IP + ':' + IntToStr(Port));
end;

Then there has to be something else happening. Either the UDP packets are
not being sent to the correct IP/Port to begin with, or they are being
blocked along the way. Is your server running behind a firewall or router?
The Trivial FTP protocol is UDP-based, which makes it harder to pass through
routers/firewalls, as they normally disable UDP forwarding by default.

Did you verify that the ports are being opened properly and are actually in
a listening mode? Use the OS's NETSTAT command-line utility to view the
active socket states.

When was the last time you downloaded it, though? The snapshot has been
10.1.5 for a long time now, but has received many updates.
