Only allowing a few URLs

[dkm60thjeep]

I have an 831 with IOS 12.3(2) and what I'm wanting to do is to only allow certain websites. I use SDM to configure and its telling me my IOS doesn't support the web filtering.

If I update the IOS will it enable webfiltering on my 831? Is there another way to block all websites and only allow certain ones?

try using nbar if you need to only allow/disallow a few sites. i'm not sure if the 831 supports it however.
