Wade, just a small word of advice. Depending upon the age of your kids, and the knowledge of computers, and i have a feeling it is relatively high. There is no long-term (a week is considered long term) solution to preventing your kids from surfing on the Internet. Parental controls can be easily bypassed, login passwords can be changed, individual cookies can be deleted along with sites, safari even now comes standard with a private browsing option, that doesn't even save the history or cookies, once they close the window, everything is gone, it isn't even erased because it simply never existed. I will tell you from experience, i just moved on to college, that there wasn't a student my age that didn't know how to get around thier parents' tricks. All routers can log history, they have range of how long, normally how many domain sites, but they can still log history. I simply ask you to consider, as a child, the respect you are wanting. It is much better to sit down, tell you kids you are able to monitor them, but you trust them and hope they will make good discussions. Remember that surfing on the web is better then being out at night, and you not knowing where they are. Your best option is probably simply having the computer in a public place. Ohh, and by the way don't tell them you "installed" a special application, they can simply look to see what currently running, check the memory and be able to tell if you are lieing. And if they catch you in a lie it doesn't matter what you caught them doing.
