Yes, but your server really ought to be able to tell it's CGI programs
how to form a complete URL to themselves.  If you're using apache
this should be possible, though I'm unsure of the details.  Probably
it involves setting up multiple virtual hosts with (slightly) different
configuration, depending on what ethernet interface the request is
coming from.

Another common solution to your problem, is to use separate internal
and external DNS nameservers, so you can have the same host name resolve
to different IP numbers depending on whether you're on your internal
network or the external internet.  (Since it's the same machine,
it should have the same name.)

Yes.  That's a fine solution.  Getting PhpWiki to do that would take
a bit of work, but you could try.  (It may be as simple as editing
lib/config.php so that SERVER_URL gets defined to the empty string.
You could try that --- I'm not sure it will work, and it probably
will break something (e.g. RSS RecentChanges).)


As a hack, you could try setting SERVER_NAME from $_SERVER['HTTP_HOST']
(in index.php, that is).
That picks up the host name from the Host: HTTP header sent by most
modern browsers.  (The Host: header is required by HTTP/1.1.)  It may
not work with a few rather old browsers.

Something like:

if (isset($_SERVER['HTTP_HOST']))
    define('SERVER_NAME', $_SERVER['HTTP_HOST']);
else
    define('SERVER_NAME', 'pick.one.com'); // punt and hope you guess
right.
