You are right, it is not actually network bridging. Rather it is
configuring iptables to forward traffic on one subnet to another.

Actually, the Debian specific documentation
(http://dev.wifidog.org/wiki/doc/install/debian) emphasizes ensuring
that iptables are correctly setup.

I figured that there had to be somewhere to specify the outgoing mail
configuration. I finally found it in config.php. The documentation
indicated that having a local mail server would make life easier but
indicated little else... like the default config being PHPMailer, which
did not work out of the box. I did not install Postfix as suggested
because I already have a server running on my network.
Anyhow, I now have a working, albeit minimal, WiFiDog Hotspot. I can
even connect with my HTC Touch! Kudos to the developers. Great job
folks! I love the idea of setting the whole thing up on a PC (router
solutions just do not appeal to me).
My WiFiDog hardware, all found laying around the house:
1. an HP Pavilion 486 MHz PC (12 or 14 yrs old?) w/ 190 MB RAM & 80
GB HD (using only about 1.5 gig of it),
2. a DLink DWL-G700AP on the lan side, and,
3. a DLink DWL-G122 on the "Internet" side.
The DWL-G122 actually connects to my main router which, in turn, is
connected to a DSL modem on a 5 Mb/s DSL line.
Best regards,
Dennis
