Stopping Open DNS - ZyXEL P660R-D1: Difference between revisions

Revision as of 12:34, 7 January 2014

The factory setting for this router on older firmware is for DNS to be open on the WAN. This will be changed when configured by AAISP, but if it is configured from new, or reset, then WAN side DNS may need to be disabled. This can be done from the web interface and setting DNS Access Status to LAN. Go to:

> Advanced - Remote MGMT - DNS - LAN

Then re-test from the Control Pages: https://clueless.aa.net.uk/dnsresolvers.cgi

The DNS checker is saying DNS is still open

If you have publicly routed IP addresses on the LAN side of the router then you may wish to disable the resolver completely instead of restricting it to the LAN, as the LAN IPs will be still be accessible from the outside world.

What is the IP address of the router?

Most routers supplied by AAISP will have a sticker or card on the base of the router which will have the IP address.

What is the admin username and password?

Most routers supplied by AAISP will have a sticker or card on the base of the router which will have the password. On the ZyXEL the username is admin.

I am Unable to get to the web interface?

Sometimes the webserver on the router stops working, try turning the router off and on again.

Changing this via Telnet

If you still can't access the router web pages, then you can do this via telnet by running the following commands:

sys server load 
sys server access dns 2 
sys save

This also applies to the P-660HW-T1 v2 Router

-If you have Static Routes setup, then disable DNS completely in the above settings page. Even though the setting is set to LAN, with a static route, the DNS will still be open due to a bug in the router.
