    "where 'n' is the name in my router's configuration."

    No, 'n' has to be the LABEL of your OpenDNS network.

    And yes, if your router allows to specify a custom update URL and does support SSL/TLS (HTTPS), then you can use the Update Client in your router to update OpenDNS.

    If your router still allows to specify a custom update URL, but does not support SSL/TLS, then you can still update via DNS-O-Matic (http://www.dnsomatic.com/):
    "http://email:password@updates.dnsomatic.com/nic/update?hostname=destination" (without quotes)

    where destination is either all.dnsomatic.com or your OpenDNS network label again.  Or omit the hostname parameter at all.

    As you don't mention the make and model of your router, we can't know if it could work for you.  Btw, alternative router firmwares like Tomato or DD-WRT support at least one of these methods.

    "Has anyone tried this method, and were the results successful?"

    Yes, I do this with my ISP supplied router (manufacturer AVM).  It allows to configure a "user defined" service with custom update URL, but does not support SSL/TLS, so I'm going through DNS-O-Matic.
    The update URL I have to use is updates.dnsomatic.com/nic/update?myip=<ipaddr> (i.e. without protocol and hostname parameter, username and password in separate fields, and as hostname I use a DynDNS one, also defined as DNS-O-Matic service, to satisfy the control and check procedure of the router's update client).

    Thanks very much for your help. I appreciate your advice.

    Is the 'label' of my OpenDNS network the name for my network on the OpenDNS website?

    I originally thought that adding the name and model of my router would be TMI but here it is: It's the Asus RT-N56U. When I get back home I'll check whether it supports SSL/TLS.

    "Is the 'label' of my OpenDNS network the name for my network on the OpenDNS website?"

    Yes, and its caption is LABEL at https://dashboard.opendns.com/settings/ - see the attachment.

    "It's the Asus RT-N56U."

    According to your manual (http://dlcdnet.asus.com/pub/ASUS/wireless/RT-N65U/E7376_RT-N65U_Manual.pdf), the RT-N65U supports the ASUS DDNS service.  This is neither OpenDNS nor DNS-O-Matic nor DynDNS.  So you can use this Update Client for nothing but the ASUS DDNS service.

    Thanks again. I thought I saw additional services in a drop-down list, besides just Asus's own DDNS service. I won't know until I go home tonight and check.

    Indeed, my router supports the following services:

    www.asus.com
    www.dyndns.org
    www.dyndns.org(custom)
    www.dyndns.org(static)
    www.tzo.com
    www.zoneedit.com
    www.dnsomatic.com
    www.tunnelbroker.net
    www.no-ip.com

    Hopefully, after not too much hit and miss, I'll get myself up and running with DynDNS.

    Great news!  So, go and register OpenDNS as service at https://www.dnsomatic.com/ and send your updates from the router through DNS-O-Matic.

    thank you, rotblitz!
    i am running tomato 1.28 and non ssl version above worked for me! I used "custom url" selection in tomato ddns and omitted the hostname parameter.
