So, coming
back to the original item on the subject: if, at least,
my main server IPs 44.134.32.240 and 44.134.32.233 were
full published and routed over the internet by UCSD any problems
here should magically solved :)
They are, in fact, published and routed by UCSD,
but there are two
problems with doing Echolink over that connection: one is that the
gateway is in San Diego, so packets from Italy have to travel to the
USA and back again to go a few km, and also the gateway at UCSD is not
a high bandwidth device, so there is considerable delay and jitter in
packets going through it. These delays and jitter are insignificant
for
things like SMTP and other non-interactive uses, but cause disruption
on time-critical connections like VOIP.
