This patch now proper allows to create rules for redirecting requests of a
given host, group or network(s) to a specified port or service to the
local IPFire system.
So it implements a very generic and easy to use feature to redirect
(for example all DNS, NTP, or whatever) requests to the a local running
instance and so to force usage of that local hosted service.
* The feature supports specifiying a single port and redirect the requests to another given one.
( For example requests to UDP 123 can be redirected to local UDP 1234
if you run an NTP server on that port.)
* It also supports direct usage of services or even service groups.
( So you can create a service group for DNS and redirect them to the
local recursor, or create a "redirected services" group which easily
can be managed...)
