"A: I do understand! In fact, I have setup the very same arrangement for remote support. But first, let's be sure everyone else understands what we're talking about, too.
"Suppose you have one wireless router. Normally when you connect your browser to this router's administration interface you do so from a client inside your LAN--that is, a client connected to the router. What if you want to connect to the browser's administration page from outside your LAN--in other words, remotely? Most routers, including those running DD-WRT, offer a separate configuration setting for "remote administration" that is often disabled by default. In DD-WRT, this setting lives under Administration/Management/Remote Access. You can customize the connection port, since the usual Web port (80) is reserved for local access. From outside the network, you connect to this router using the IP address assigned to the incoming broadband connection (or use a dynamic DNS service to translate the IP to a friendly name).
"Now suppose that the LAN in question is served by two wireless routers, configured to extend range through either a repeater or WDS configuration. You want to remotely admin the second router, but how do you address it from outside the LAN?"
