One thing that O2 didn’t put into the web interface for the Thomson TG585 wireless routers they supply you with, is a way to change DNS servers. It’s therefore a bit of a pain if you want to use OpenDNS. Luckily it’s not that hard to make the changes via a telnet connection:
telnet 192.168.1.254 Login name: SuperUser Password: O2Br0ad64nd
Now make a note of your existing DNS setup using this command:
dns server route list
It’ll give you something like this;
DNS Server Entries: DNS Server Source Label Metric Intf State Domain D 87.194.0.53 10 O2_ADSL UP * D 87.194.0.52 10 O2_ADSL UP *
The ‘Intf’ column is the type of connection you have (yours might differ from mine).. you’ll need this for the next commands;
dns server route flush dns server route add dns=208.67.222.222 metric=0 intf=O2_ADSL dns server route add dns=208.67.220.220 metric=0 intf=O2_ADSL dns server route list saveall
That’s it. Release and renew your IP address on all connected equipment and you’re all set.
