Hija,
sorry for sounding a little lost here but that's probably because I am.
Let me explain what I'm trying to do:
I've a gateways with one uplink and several disjoint networks beneath it
like:
| T1
---------
| GW |
---------
/ \
------------- -------------
|10.0.0.0/24| ... |10.0.5.0/24|
------------- -------------
Now what I need is to simply classify users in the network segments into
speed classes (gold/silver/bronze) and cap their traffic at fixed levels
inbound and outbound. My idea was to simply add one class and one filter
per used ip which should be no problem, however I have no idea how to
get rid of this class and filter once the user vanished or replace it by
another value when a different users shows up taking the same address.
The problems are: How do I figure out the tree id from the ip? Or how
can I reconfigure the limit without knowing the id?
A different idea would be to add (say) 500 classes for each speed level
and remember the used/unused ones in the application and serve the next
free class to a user by creating a filter on logon and removing that
later on.
If you now say: Hey, that pretty easy; please hold on. :) Additionally I
don't know the addresses in advance because they're either served using
DHCP or set up in a fixed manner and routed thanks to arpspoofing so
this doesn't seem to make a good case for hashing. Also I somehow need
to also take care of the traffic which goes through transparent DNS and
http proxies.
Any help and ideas would be greatly appreciated.
