Problem with airport express second generation

[efesios]

Hello, in my house I have the router provided by the ISP, but I have not been given access to reconfigure DNS, I am waiting.

We manage two wireless networks, one connected to a Linksys EA2700 router and another to a second-generation Apple airport express.

In the router linksys already reconfigure the DNS and when I am connected to that network I work perfectly the parent control.

But in the airport express, although I also add Open DNS, when I connect to this network does not work and I do not block the sites.

If you can help me please.

Copy & paste the complete plain text outputs of the following diagnostic commands to here, from a computer connected to the Airport Express:

nslookup -type=txt debug.opendns.com.
nslookup -type=txt which.opendns.com. 208.67.220.220
nslookup www.exampleadultsite.com.
nslookup whoami.akamai.net.

You clearly do not use OpenDNS to send your DNS traffic to, but your ISP's DNS service, indicated by 74.125.184.1.

Ensure that you configured your Airport Express router at 192.168.100.1 or your computer only with OpenDNS resolver addresses, and that you filled all offered DNS server fields only with these OpenDNS addresses.
