[SOLVED] DD-wrt how to change dchp default gateway

MrUmunhum · 04-19-2016, 03:31 PM

Hi group,
I have a LinkSys wrt54g router with DD-wrt install (Firmware: DD-WRT v24-sp2 (08/12/10) micro). DHCP is enabled. By default the DNS is defined as the router's IP address. I need to change the default DNS but I can't find where to change it. It is not in the setup=>basic setup tab under 'Network Address Server Settings (DHCP)'?
I do have telnet access.

Anybody know the secret handshack to define the default DNS address?

Thanks for your time.

Code:

ISP DNS-Servers

If you wish to pass through the DNS servers from your ISP, you can use the following parameters:

dhcp-option=6, x.x.x.x, y.y.y.y

where
x.x.x.x = DNS1
y.y.y.y = DNS2

[edit]

The secret is where to place this info:

Code:

Extra DNSMasq options

There are some extra options in the web interface for DNSMasq that you can set by entering them in Additional DNSMasq Options on the "Services" tab.
