[squid-users] Accessing a transparent cache on localhost

Hi,

I'm new to Squid. I've successfully set up a transparent cache on a
server which is also the gateway/firewall/NAT for a small LAN. All the
clients on my LAN use the cache properly. However, the server running
the cache doesn't use its own cache. I've inserted what I thought were
the correct rules into my iptables config:

-A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128
-A PREROUTING -s 127.0.0.1/32 -p tcp --dport 80 -j REDIRECT --to-port 3128
-A PREROUTING -s 192.168.0.1/32 -p tcp --dport 80 -j REDIRECT --to-port 3128
-A PREROUTING -s x.x.x.x/32 -p tcp --dport 80 -j REDIRECT --to-port 3128
(external public IP)

where eth0 is the LAN-facing interface.

My Squid config allows proxying from localhost and localnet:

http_access allow localhost
http_access allow localnet
http_access deny all

Therefore I think I have not set up my iptables quite right. Can anyone
confirm if this is the right way to go about catching HTTP requests from
localhost?

Many thanks,
Jonathan
