Maybe he doesn''t want to assign "real" IPs on the LAN?
Unfortunately,
in some places, there could be political or practical restrictions that
would make it inconvenient to get additional real IPs. Anyway, I am
about to try a similar set up myself for testing.> On Sun, 2006-10-22 at 16:15 +0200, Andreas Heinecke wrote:

I think you might be running into a problem with NAT, proxy settings,
and/or HTTP pipelining in apt, I have had similar problems with the
behavior triggering IPS on SonicWALL and getting blocked. Try this:
Comment out proxy line if it exists in /etc/apt/apt.conf
// Acquire::http::Proxy "false";
Create a file /etc/apt/apt.conf.d/80http containing:
// /etc/apt/apt.conf.d/80http
Acquire::http::Pipeline-Depth "0";
Alternatively, set up an http proxy on the LAN that can get to the apt
repositories and configure the domU''s to use the proxy--if you have
multiple domU''s using the same OS version, this will have the side
benefit of cutting down on WAN traffic to download updates.
apt-proxy looks nice since it stores cached files in a format where you
can also access the real files on the filesystem. However, I couldn''t
get apt-proxy working, so I ended up using squid, but there is no easy
direct way to access files that are cached by squid.
