I think I have a similar setup with Xen 2.0.7, but not the same problem.

Just to make things clear:
a) in which direction does the download go (from domU to net, from net 
to domU, from dom0 to net, ....)?
b) did you setup iptables manually or do you use something like 
shorewall for that?
c) what exactly is script-nat?
d) did you test if connection is reopened after some time (5 minutes, 
one hour, etc.)?
