Proxy

squid - reverse proxy

Great guide here - http://www.classhelper.org/articles/reverse-proxy-server-squid-debian/installing-squid-proxy-server.shtml

I’ve modified slightly for Ubuntu, but almost identical.

apt-get install squid cp /etc/squid3/squid.conf /etc/squid3/squid.bak rm /etc/squid3/squid.conf nano /etc/squid/squid.conf

Using netsh to create a transparent proxy

There are some good windows web proxies about. The only problem with them is they sometimes dont natively act as a transparent proxy. i.e. typically you’ll need to set your client machines to a specific IP and port.

I’ve used squid historically when setting up transparent proxies (mainly since it actually has a transparent mode) and this has worked well. Recently i thought i’d have a go at some of the windows solutions to see how they pan out.

squid - your transparent proxy friend

Still my favourite light and fast web proxy is Squid. Its very easy to setup and get running on almost all flavours of linux. You can find it here http://www.squid-cache.org/ but will probably find it in your local package manager…

This is for more my own reference… as i don’t think too many people have the need for a transparent proxy. You only need one NIC configured on your VM / machine as its most probably on the same subnet as your dsl etc…
