I have been working as an admin on a WAN comprised of multiple linux
servers (and associated [irrelevant] Sun Ray clusters) for a short
period of time now. Until this point my tasks have been primarily
comprised of configuration of different security and authentication
services with a few package installation and configuration tasks and
scripting thrown in for good measure.
I've just been given a new task to begin when I'm completed with the
one that I'm currently involved in. Being as my current one only
consists of me babysitting downloads for another few hours, I decided
to start researching the upcoming one.
The office that I work at is connected to several satellite offices
via 3 separate dd-wrt openVPN linksys routers. Each is a separate
gateway, 2 for specialized services and one for general internet and
GNOME desktop traffic (which is normally on the local subnet of the
WAN to conserve bandwidth). Our current projected expansion has my
superior thinking that it would be a good idea to replace these 3
linksys routers (and their associated 200MHz processors) with a
dedicated linux routing machine, short on memory and HDD space, with
1GHz or slightly higher processor so that we can handle whatever
bandwidth needs we're thrown in the next year.
So I started googling, as it is to be my task to set up that machine.
Unfortunately, although I'm familiar with the basic concepts and
terminology used in networking, I'm relatively deficient in practical
experience. What I'm looking for is information on using the linux
router to connect to the other dd-Wrts utilizing the same VPN
structure as was utilized before. I have not been able to find
anything except for information on connecting dd-Wrt devices to each
other. Thus I'm looking for any tips or pointers to information on
configuring such a setup, or any explanation of how existing
documentation can be used with a few changes, etc...
I'm also interested, for curiosity's sake, in how much information
these dd-Wrt devices can actively handle with their processing
capabilities (both with and without SSL/TLS overhead).
Thank you for any help or comments you might have. :)
