After installing DD-WRT Firmware you can access the DD-WRT Web-GUI using a web browser pointing to the same IP address as before you installed DD-WRT. These are some of the most common default IP addresses: 192.168.1.1 (most commonly used on Linksys and Asus), 192.168.2.1 (some Belkins), 192.168.11.1 (some Buffalos), 192.168.10.1 or 192.168.30.1 (some Motorolas), and there may be others.
If for some reason you completely lost web access to the router, the web server (HTTP daemon) may be shut down. To regain access try starting the web server. SSH or telnet into the router and enter the following commands:
httpd -h /www
To connect through secure HTTP, add the option -S at the end of the command. See the httpd man pages for more information about that command.
You can use this feature to get a more secure router by activating the web interface only when you need to configure it, and then closing the web server once you're done.
To shut down the web server, run the command kill `cat /tmp/var/run/httpd.pid` (note the backquotes) or kill `cat /tmp/var/run/httpsd.pid` if you ran the web server with the option -S to get secure HTTP.
Method 2: If you're at a remote location and have access to your router through SSH or telnet, but you'd like to enable remote web access, you may use the following command to allow access from one remote IP address:
This temporary remote web access will be disabled again when the router reboots (unless you turned Remote Administration on from the settings in the web interface or saved this as firewall script under Administration ->Commands).
