"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?"
