RE: [squid-users] Re: transparent caching

Hi, Gareth and others,

My situation is like part of you said, I am using the proxy server as a "gateway" and the clients are not aware of it.

I am setting the squid to run on port 80, with only this configuration.

***
http_port 80 transparent
***

For experiment, I have no rules in IP tables, and it's turned off. It's basically working, at least for HTTP for now.

Please also check this post: http://www.deckle.co.za/squid-users-guide/Transparent_Caching/Proxy

Thanks,
Shan

Hi Shan,

If you are running Squid as a forward proxy, for example as an Internet gateway, you would normally have a firewall (device or server running
IPTables) that your users would pass through. The idea with transparent proxy is that your users would have no idea they are being proxied, that is you would not normally have to configure a users browser to go via the proxy.

Instead, you set your firewall to capture all traffic on port 80 (from your internal network) and pass that transparently to your Squid server (which usually runs on port 3128).

User browses -----> Firewall forwards ---------> Squid listening on 3128
to a website port 80 requests deals with the
request

If you set your Squid server to run on port 80, you could still run it as a transparent proxy, you would still need to do the port forwarding from your firewall to the Squid server.
