Transparent squid and apt-cacher on the same box

[Dayo Adewunmi <contactdayo@xxxxxxxxx>]

Hi all

I've got squid 2.6.18-1ubuntu3 on an ubuntu hardy box. This box is the 
firewall and squid's on there  too, running as transparent proxy. I have 
apt-cacher-ng on a separate box behind the firewall serving package 
management on the LAN. by streaming from the internet. This works fine.

Previously, I was using apt-cacher (not -ng) on the firewall itself, 
serving the LAN. This worked fine, too, until I turned squid into 
transparent. Now I'm getting 403s whenever I try to run `aptitude 
update` on the firewall. Does anyone have any experience with getting 
apt-cacher (not -ng) to work on top of a transparent squid box?
Thanks

Dayo
