[freenet-support] Changing ports etc.

[Level 13]

Is there a short how-to for Freenet 0.7 installation for those who are
switching from 0.5? Especially I'm looking for info about:
-how to change the default ports (which are already taken by other
services on my server, and are not to be used at all), for local
access as well as the one visible on the outside,
-where to put the hostname.dyndns.xyz info so that you can be reached
if you have a dynamic IP?
