    Hi,

    My Fritzbox 7340 is the ADSL router for internet access, while I have all my wireless clients setup to use my Airport Extreme wireless network. The Airport Extreme is wired to the ADSL router. The ADSL router is also serving as DHCP server in my network.

    Now, I've followed the steps to get the OpenDNS entries in the Airport Extreme, which went well. However, none of my wireless clients seem to using these DNS servers. I fear that, since the router is the DHCP server, my clients automatically use the DNS servers from the router.
    To make matters worse, there is no easy way to change DNS servers in the router. Further the router is also linked to IPTV from my Internet provider, so I probably can't even change them even if I tried.

    Any hints? As a temporary measure, I've set the DNS servers for all clients locally, but that is not the preferred method.

    Thanks!

    You say it! Or better, they use the router as DNS server.

    "Any hints?"

    Sure, two options:

    1. Disable DHCP on the Fritzbox, and enable it on the Airport Extreme.
    - or -
    2. Configure the Fritzbox with the OpenDNS server addresses and see if it impacts IPTV. I have a similar AVM router with DTAG as ISP, and it doesn't impact IPTV (Entertain) and VoIP (7 SIP providers - non-DTAG).

    Hi, I tried the second option, after learning the the DHCP server of the Airport Extreme only lets you set the ip range from 10.0.1.xxx, while all my ip addresses are in the range of 10.0.0.xxx.

    Anyway, Fritzbox now uses OpenDNS servers and IPTV is still working.

    Thanks!

    Happy to hear you got sorted. Just one comment on:

    "the DHCP server of the Airport Extreme only lets you set the ip range from 10.0.1.xxx"

    If your clients are all set to obtain their settings via DHCP, the IP address range doesn't matter. They will all change to 10.0.1.xxx without problem.
