    Hi all,
    I just moved to HOT, a local Israeli TV/Phone/Internet supplier.

    I am using a Segacom F@ST 3184 modem/router.
    The DNS there is fixed to the company DNS.

    How can I still use OpenDNS?
    Must I go to each PC on the network and change their DNS from automatic to static with the correct numbers?

    Is there another, simpler/safer, solution?

    Thanks,
    Oren

    In the UK we have BT and their homehubs which also are not configurable for dns settings.
    I managed to use my old router and disabled the dhcp on the BT new router. I then enabled DHCP and dns on the old router. The old router was connected as a slave via the lan port to the BT router. What you get then is that the old router provudes dhcp and dns which points to OpenDns to all my network devices.
    I got the original instructions here http://punj-technology.blogspot.com/2011/02/using-opendns-with-bt-homehub-broadband.html

    Hope the above helps

    "Must I go to each PC on the network..."

    In case you have so many computers, it's worth to think about an own internal DNS server. This can be an old computer with a free DNS server distro like BIND.

    Hi Oren. I also moved to Hotnet today. As you say, there's no way to change the DNS setting in the Hotbox. I did have the OpenDNS addresses plugged in on each client device, but the resolution time is VERY slow. I ended up just putting the Hotbox's address as DNS instead. Did you find any way around the limitation? I have around 6-7 PCs and device on the network. Not sure if that makes having an internal DNS worthwhile, although it'd be an interesting project for sure :)
    :wink:

    What you also could do is to put another router behind the ISP's device, configure this with OpenDNS, and connect all devices with this router. Or simply exchange the ISP's device by another router if possible.

    But before taking any efforts you must ensure that you can use OpenDNS at all:
    nslookup -type=txt which.opendns.com. 208.67.222.222

    "configure dhcp to distribute open dns ip's upon all clients"

    Bad idea. It is really suboptimal to have external resolver IP addresses on local devices. This is not where they normally belong to as this breaks or at least impacts local name resolution.

    If a server is used, then a DNS server software like BIND belongs onto this, and the OpenDNS resolver addresses are to be configured as forwarders, not on the DHCP side.
