[AuckLUG] Dynamic IP Address XTRA

[Ravi Chemudugunta]

I am on the Go Large (haha) Plan, my IP stays the same until I restart my
router - but sometimes it will drop the connection and assign a new IP
address.  Personally I don't see how ISP's will be able to cope with
allocation of IP addresses since everyone with an broadband connection will
have one ... whether they are using the connection or not, since most of
them are 'always on'.

With the port 80 issue, AFAIK xtra doesn't block incoming ports (except
torrents?).  You can't access your server using the external IP from inside
the LAN, you need to use your local address - something like http://10.1.1.x

This can sometimes be a pain when you are scripting web pages, as the root
address changes (i.e. http://10.1.1.x within your lan and
http://something.com from the outside) - to fix this add an alias in your
/etc/hosts file for e.g.

...
10.1.1.8        blakbox.ath.cx
...

So whenever you type in your web address (this is my dyndns.org one) it
won't resolve to your external IP but give you the internal IP.
