internet guide and apple airport time capsule

The IP address you use shouldn't be one from documentation, it should be the one for the service you want people to connect to. That probably will be the dynamic IP you refer to.

Your Internet Guide defense plan not consistently working can have these most likely reasons:

• You're currently not using DynDNS for your DNS lookups. Check it here.
  If it says you're not using Internet Guide, check the place where you have configured the IG DNS server addresses 216.146.35.35 and 216.146.36.36 and correct this, as Cry Havok said. If your router has more than two DNS server slots, fill them all! Also, check your computer for DNS server addresses other than the router's IP address or IG server addresses. Computer DNS settings usually override router DNS setttings.

• The IP address for the hostname associated with your defense plan is no longer updated.
  See if you have a problem with your DDNS Update Client and correct this, or perform the update manually.

• You have more than one network/hostname configured, and each has a different defense plan, so that you use the one or other randomly.
  Correct this while having only one network/hostname for your current IP address in Internet Guide, or more than one network/hostname, but all with the same defense plan assigned then.

• Your current IP address is registered with another network/hostname at DynDNS used for IG, no matter if your hostname or someone else's. Also in this case you may be using randomly your defense plan or someone else's defense plan.
  You can solve this yourself only if you try to obtain another IP address from your ISP, e.g. by disconnecting from and reconnecting to the internet. Don't forget to check if the DDNS update for your IG assigned hostname has taken place then.

Here's my novice summary (thanks to help fromCry Havok and RotBlitz)for Airport Extreme / Time Capsule users wanting internet filtering/protection with Internet Guide:

A. Get/purchase/register a unique "custom" domain name and set it up according to tutorial for airport and custom DNS

B. In the advanced DNS preferences for for your custom domain, make sure all your domains and subdomains point to the IP supplied from your ISP, probably the IP from http://checkip.dyndns.com/ Do NOT use IP 204.12.249.212 shown in the picture- a red herring for fools like me.

C. Under Internet:TCP/IP set airport's two DNS servers to internet guide's DNS servers, 216.146.35.35 and 216.146.36.36. Your dynamic global host settings with tsig and key should have been set from tutorial on airport and custom DNS

D. Save your airport's configuration by exporting it in airport utility. Consider resetting airport to factory settings then reload the configuration you just exported. Otherwise airport seems to have unpredictable behavior. (similar flakiness with a new cable modem was resolved by factory reset of airport.) Note: I did not need to factory reset my airport expresses that extend the airport/time capsule router's network.

E. Set up a defense plan in internet guide. Add a new network. You should see (at least) the options for your customdomain.xxx and your airport's name.customdomain.xxx. Just choose the domain.xxx and pick your defense plan.

F. Make sure all computers, smart phones, wi-fi extenders (like airport express) have their DNS servers default to the airport router IP by leaving the DNS fields blank or set to the default DNS of a factory reset airport, 10.0.1.1

That process (finally) worked for all devices connected to my airport router's network.

Extra: To check if filtering is working without bringing up an offensive site, blacklist an innocuous site in your defense plan, (something like "www.crazy.com" and type it in your web browser. It should be replaced with a blocked page from Internet Guide.

If filtering stops then it suggests that your DNS servers have changed. Have you checked that they are still set for the Internet Guide on the Airport and that each computer has the Airport as their DNS server?

Well, I was going to post images of my settings, but "sorry, new users aren't allowed to use image tags" Thanks DynDNS!

Anyway, my custom root domain is http://xxxxx.com Type A IP 204.12.249.212, which points to a virtual server. Is this IP correct or is it to be the same as my dynamic IP from the ISP. I got the 204.12.249.212 from the Airport tutorial?

Thanks for help.
