Hi MrCharlie. I took a look through that manual but its not very helpful. I did notice a couple of things that might get you on the right track. I'm not sure though.
Here are my three ideas.
1) It appears that you will have to change your WAN Type setting from dynamic to one of the other settings if you can find a compatible one. That would depend on your type of internet connection. I noticed that if you use PPPoE, you can specify primary and secondary DNS settings (required for OpenDNS) but you can leave the IP address blank so that it is still automatic as provided by your ISP. PPPoE is used with a DSL connection with the modem setup in "bridge" mode, usually. The other option (which the manual does not show) is STATIC IP. Maybe, and just maybe, you can go in to that setting, and specify primary and secondary DNS settings and leave the IP address settings blank so that they will remain automatic?
2) I notice there is an advanced button at the bottom of the configuration page, maybe there is an option to specify DNS servers in there somehow. The manual is just too limited to show me what you might see.
3) I also notice a DHCP link at the bottom of the configuration page. Maybe you can modify the DHCP settings and make the router give out a different Primary and Secondary DNS setting to your workstations when they request IP information from the router. Normally the router would probably point your workstations at the router for DNS requests, but if DHCP settings can be modified you could make it provide a different address for DNS. This would place the "burden" of using OpenDNS on the workstations rather than the router.
EDIT: One last after though, if the above doesn't work. A firmware upgrade may provide more options if you haven't tried that yet.
I forgot to mention I connect by cable so its a cable modem to the router and then to the computers via cables.
So far as a firmware update, can't do that….it's no longer supported.
Let me understand this, there's no sense configuring the computers for OpenDNS if they're behind a router…is this correct?
The router has to be configured for OpenDNS…..correct?
The only place I see that you can enter OpenDNS settings is if I go to setup and then Static IP Address and I can't leave the IP adress blank…it won't let me.
I've attached to pixs one of the info page and one of the Static IP Address if that helps.
After configuring it, I went ot test if it was working and they said no.
Is there anything of use under the "advanced" or "DHCP" link on the bottom of the configuration page?
Sometimes DHCP can be reconfigured to give a particular DNS setting rather than the default.
As far as programming it on the workstations. Yes, you can just do that if you want but is a bit more tedious. It would be nice to get the router to handle it. To program it on the workstations just set the DNS entries manually.
Its been a while since I used OpenDNS. But upon taking a closer look. If you are wanting to use OpenDNS to filter your web traffic then I think you will be forced to use the dynamic IP updater client on one of your workstations so OpenDNS can recognize you. Some routers may have the ability to update that info for you automatically, but I doubt yours does.
This only applies if you have a dynamic public IP address, like most users.
EDIT: Sometimes the cable modem can be configured to use a particular DNS setting also which would be effective. The cable company support may be able to assist you with that. Obviously, by default, it would use the ISP's DNS servers, but that may be able to be reconfigured. This would eliminate the need to configure the router.
Have a good holiday….. MrC
