Router with easily whitelisted content filtering

[shrnky]

Looking for a router with content filtering that would easily allow someone to white-list a site without having to log into the router directly.

I have many small business customers who constantly call me when they need to white-list a site. They don't like it and neither do I.

It would be great if the blacklisted webpage shown when a site is denied had a place to enter a password to allow it in the future. This way they wouldn't have to get into the router and risk messing anything up.

Any thoughts or suggestions would be appreciated.
