Accessing Blocked Websites – Use your own proxy server at home!

It is getting bizzare. Many corporates erroneously blocked Gmail since it got reported as a virus! On top of it, all are busy blocking Orkut and Myspace. I had written a recent piece on accesing banned Websites. Most of the methods mentioned there don’t work in corporate networks since network admins are also getting smart :)

One of the methods I mentioned was number 8 – Your own proxy server. This is superior to all other methods due to a couple of reasons. First free public proxies are never safe. Your personal and private information can be compromised in these servers. Also these will get blocked by the proxy software eventually. Another reason is that using your own proxy server gives you complete control. You can encrypt your traffic so that no one knows what is being browsed.

I will look at setting up a Http proxy server on a Windows XP machine. Please note that this article won’t be covering the case when you use proxy server or WiFi at home. I will be writing another post about such scenarios later.

Step 1 – Download and install Perl distribution
Download Windows x86 version of Active Perl from ActiveState site. Install with default configuration except the directory which I recommend to be set to “C:\usr\”.

Step 2 – Download and install Apache server
Download latest Apache server for Windows (2.2.3 as of today) from Install it under any folder with port 80 as the HTTP port . Setting port to 80 is important since most corporates only allow port 80 access. If you get any error in binding to port 80, probably you have something else listening on it.

Step 3 – Configure Apache server
Now we need to configure Apache to enable CGI.

Locate #AddHandler cgi-script .cgi in httpd.conf (located inside apache subfolder conf) and remove the hash(#) in front.

Locate the “you set DocumentRoot to” string in httpd.conf. Under that you will see Option directive. Change it to Options Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

Step 4 – Download and install CGIProxy (nph-proxy)
Download CGIProxy (nph-proxy) from Rename the file to nph-proxy.cgi and copy it to Apache’s document root (htdocs). Now change the first line in nph-proxy.cgi to #!C:\usr\perl\bin\perl.exe

Start Apache from the bin folder (httpd.exe). Now open a browser session and point to http://localhost/nph-proxy.cgi. If everything is ok you should see the following screen.

Using home made Http Proxy

Find the IP address of your home connection. This can be viewed by typing ipconfig on the command prompt. Now from the office machine access http://IP ADDRESS/. You should see the proxy form which we saw above. Happy orkutting! :)

Note : This will need more steps if you have a WIFI network at home (port forwarding). I will cover these issues in the next post.
