Thanks, I plan to move pulp_streamer to my firewall/edge box (that has
a bit more resources to handle larger on_demand requests), I also have
squid running there already. Now is trying to figure out how to route
request to pulp_streamer or instead setup a dedicated varnish 'Reverse Proxy'.

In respect to removing the middle man (varnish), I only have 5-7 boxes
(LXC) registered to pulp. It seems unnecessary. Right now, the pulp box
is connected directly to the Internet (Port 80 and 443 is not filtered
for this box) and not configured to work with the Squid proxy on the
lan network. For now, I've decided to, as mention above, move
