This is a guide to setting up OpenDNS and DNS-O-Matic to filter Web Traffic for free using a Buffalo ADSL2+ Router [WBMR-HP-G300H] running DD-WRT v24-sp2 (12/21/11) std – build 18026.
STEP 1 OpenDNS
Sign up for an account with OpenDNS, open your email client (or web mail) and Confirm your account, add the network ip address listed and give it an alias i.e. “Home”
Goto your OpenDNS Dashboard click on Advanced Settings to ensure Dynamic IP Update is checked
STEP 2 DNS-O-Matic
Goto DNS-O-Matic and sign in with the same login as OpenDNS and set up a service link to OpenDNS ensirinmg that the Network Label is that used as your OpenDNS alias
STEP 3 Your Router
Log in to your router and Set the DNS Servers to IP address: 208.67.222.222 208.67.220.220
Set up DDNS in router as follows
DDNS Service: Custom
DYNDNS Server: updates.dnsomatic.com
User Name: ********@***.***.**
Password: ********
Host Name: ********.dyndns.org -a Home
URL: /nic/update?hostname=
Note in may case I also have a dyndns name which I use, so I think the hostname for you to use would be simly “Home” without the quotes.
STEP 4 – Tweaking
Goto OpenDNS Dashboard –> Settings and set the filtering level you desire in the Web Content Filtering section. Here you can also set up your exceptions as a black list (Always Block) and white list (Never Block)
