You unplug that cable going to your internet connection and/or disable the WLAN adapter on the computers. Please note that these computers do no longer receive automatic updates then.

That is useless. I have an old XP machine, and kids videos and music are on my local network. I want the XP machine blocked from WAN access but allowed LAN access.

"That is useless."

Maybe for your purpose or from your perspective, but generally it is not useless.

"I want the XP machine blocked from WAN access but allowed LAN access."

This is a different scenario. If your router supports this, block internet access for this device. Else go into the TCP/IPv4 properties of the computer and configure 127.0.0.1 as the only DNS server address. This does not really block WAN access, but it disables DNS.

If you really want to block WAN access, you'll have to introduce IP address blocking rules with the Group Policy Editor, or you configure persistent routes to point all IP addresses outside your network range to nothing.

Btw, all of this has nothing to do with OpenDNS. Did you think it had?

I want to apologize. My frustration stemed from the fact the my otherwise nice netgear router logged me in to opendns to access parental controls with content filtering and only 4 options for it. Other routers. I have owned provided numerous options including individual blocking. I also assumed I was at a netgear site, not opendns. Thankyou for somehow knowing what I wanted and I apologize again for my rudeness.
