Here are the basic command lines that comes in handy while working with the DD-WRT firmware via terminal.

Basic Command Lines

What is an update client?

An update client is a computer application or a feature in your router that keeps your hostname's IP address up-to-date with your registered domain name. Your IP address sometimes changes IP address (monthly, weekly, or even daily) without your notice, and this may cause all sorts of issues for client's using the domain name linked to a certain IP address. This update client is for DynDNS users.

Setting up VPN on the DD-WRT firmware is an intermediate tutorial due to complex configurations and security settings. For those who doesn't already know what PPTP (Point-to-Point Tunneling Protocol) is; PPTP allows you to connect securely from a remote location (such as your office, home, or school) to a LAN (Local Area Network) designated at another location, such as your workplace/office.

Note: PPTP has some security flaws and is considered deprecated. An alternative you may find just as easy is OpenVPN.

To setup a VPN through PPTP, login to your web GUI (http://192.168.1.1) and navigate to Services > VPN where you will see under PPTP Server, disabled by default. Select Enable and fill in the following information accordingly.

NTP Client (Network Time Protocol) is a software client that allows your router to sync it's time from a time server. If you haven't already set this up for your router, you might want to look into setting it up -especially if you're "Access Restrictons" and the "Traffic by Month" are enabled. If your router isn't synchronized with the right time, you may encounter some major problems with some services that the router has that uses dates and time to determine it's output.

Setting up the NTP client is easy if you know your time servers. To configure the NTP client, navigate to your web GUI (http://192.168.1.1) > Setup > Basic Settings and scroll down to the NTP Time Section.

1. Select "Enable" for NTP Client.
2. Choose your Time Zone for your location.
3. Set the Summer Time (DST) accordingly (See Time Zone settings below)
4. Enter the domain name or IP address of the Time Server.

Setting up your home web server is a fairly easy thing to do and deals mainly with port forwarding. However, there are a few settings to be configured and programs to install before your web server can be up and running.

If you're running Windows Server Enterprise 2008, there's a few settings you need to make on the operating system. But first thing first, you want to register your IP address with a domain name. There's plenty of free DNS services offered for this, but one of the most popular and widely used is DynDNS.org.

To do this visit DynDNS.org, create an account, and create a new host. Make your hostname and choose a domain name for it. Check the "Wildcard" box and choose "Host with IP address" for Service Type. For your "IP Address" click the link right under it that says "Your current IP address is: xxx.xxx.xxx.xxx" to automatically link your IP address to this hostname. Once you've completed those steps, click Activate to .. activate your hostname. The next step is to download the DynDNS Updater. This program automatically updates your hostname with your connected IP address, because every so often your IP address changes, and will require a manual IP update without the DynDNS Updater. You can download the program here: DynDNS Client Updater.

You can optimize your wireless connection for both a single router in a network and/or multiple routers setup as a wireless client bridge. This is fairly easy todo. With just a few minor changes to your wireless settings, you'll be able to optimize your connection speed.
