maybe the adults should just have trust and faith and understand, and just just try and lock them out

I also find it useful to install remote-access software (such as TightVNC) which allows me to see what's happening on the kids' computers at any time.

Protection against your children is more than just having routers to stop them (or malicious software they accidentally download) from accessing your computer. There are also other legal issues. My ex's oldest liked surfing for porn and he couldn't understand that if he went to the wrong site (e.g. child porn) that he could get me into legal trouble using my computer to surf. Most people don't think of this. Even with what I did to lock down his account, he was still able to surf for porn at times...

The suggestion given if u hav more than one PC.But the better solution for guys like me who have only one PC will be to recommend some parental control softwares.I am bit disappointed with leo's reply

Parental control software, which I've discussed in earlier articles, is intended to solve a different problem. This article specifically addresses the situation where you have multiple computers in the house, someo of which you trust, others which you do not.

If you go back to origin of the question it was all about network protection NOT website and surfing protection Hence the LAN & WAN explanations.......WELL Illustrated Leo

I agree with Leo that this is a good thing to do and expanded on it a bit on my blog
A second router protects adults from kids

What do you do if you need to access shared files across the Parent - Children network? All my Installation files for drivers/software are stored on my Windows Share on my computer (Parents) but it needs to access by all other computer for installing. Same goes for my media (music + anime) that is stored on Parent computer windows share.

Is there simple way to allow access to windows share only under router B (Parents router)? My network internal isn't really setup for LAN safety, though I already do have 2 routers. I just have LAN connect to one of switch port (LAN) of 2nd router instead of using WAN port. Would nice to do so if I knew easy solution for file sharing.

Not really. In a sense, either you're protected or your not. Opening up for file sharing is breaks a hole in that protection. There are (somewhat complex) solutions but by the time you put them in place you're actually better off not having the additional router and using software firewalls everywhere instead. It's not as bulletpoof, and thus there is additional risk, but it's also not as complex to share files.

If you feel you need protection from your kids computer(s), I wouldn't set up file sharing, but rather look at other alternatives like moving USB drives around (which has risk, as infections can travel) or burning stuff to DVDs.

Might be worth doing an article on the benefits of using Linux for Internet/email/Office doc useage, Leo. IMHO, Ubuntu (and probably other flavors) are ready for prime-time, and by adding ClamAV, you won't pass on infected email attachments to hapless Windows users.

Couldn't you accomplish the same thing by assigning static local IP addresses and using two different subnets?

What if the kids computer get infected with spyware? Wouldn't malware that is Sophisticated enough might be able to use ARP poisoning to route all your traffic (from both routers) through the infected machine and harvest sensitive information. Probably won't compromise stuff like banking which is encrypted, but certainly it could steal stuff like email passwords that are sent in the clear.
