There are two ways to limit access to sites:  Either eliminate access to certain sites, or better yet( at least initially),  have access to only a few sites eliminating all the others!  Yes, have access to only 5-10 sites!  Yes, it is possible to still live without them!!!

Internet Explorer can be configured to restrict access so only a short list of approved sites can be accessed by anyone without a special password.  You will have to work with another person who would have the password.

Limit your sites to your bank, your work sites, your e-mail account.  This can be very restrictive but Mt.  5:30:  “If your access to the internet causes you to sin, cut it off and throw it away.  It is better for you to lose access to the internet then for your whole body, soul, and computer to go to Hell!” …okay, a loose translation but you get the point!

To find out how to do this search: “How to limit access to sites on the internet?” and you will find sites such as http://www.boutell.com/newfaq/browser/restrictie.html which tell you step by step how to do this.  Another site http://www.timeatlas.com/web_sites/general/methods_to_block_websites describes 5 ways of doing this.

Finally go to http://internet-filter-review.toptenreviews.com/ for an internet filter review that grades filters that allows limits only to certain sites (or eliminates sites).

All of these ways will require you to have a partner, sponsor, or trusted friend to create the password that you will not have access to, no matter what. 

Most, if not all, internet filters can control the amount of time you have access to the internet.  The internet filter account would have to be established with someone other than you as the “account holder.”  Meaning, you have to have your wife, accountability partner, priest, or sponsor to change any settings you set.

A time control allows you to schedule the time of day you have access to the web.  Let’s say you struggle with pornography in the evenings or night.  Limit your access to only 8am-5pm; or perhaps you only need to be online to check messages and just a small amount of work on the internet in the day.  You might set the time limit to be only an hour or two a day. (for example:  http://www.internetsafety.com/monitor-internet-usage-with-time-limits.php )

Once you have established a long period of sobriety from looking at pornography (3-6 months), then you can slowly increase the amount of time. Any relapses would result in an immediate return to strict access time until you are stable.  Limiting the amount of time or even which days you have access is one of the best tried and true ways of creating a period of sobriety so you can work on prayer, relationships, and healthy entertainment, thus eliminating any need to be impure.
