Tables are invaluable for several functions. The most important to me is
the ability to create a 'block' list that can be easily updated from a
program or script. With a table you just need:
add 00500 unreach port ip from table 86 to any
in your standard configuration and then a script can do:
table 22 add 2001:400:14:23::45
to add a system to the list. To do it without tables means finding an
available rule and inserting the rule in the main table.

I can do it without tables, but it works much better with them.

Hi,
I developed with Luigi (as mentor) and Mariano Tortoriello the first  
release of ipfw with ipv6 extension. If you and the FreeBSD Community  
think that the tables functional  is a good feature i can develop it  
for IPv6 protocol.


Ciao

With all of Luigi's excellent work on ipfw, I'd like to request that
someone familiar with the code look at implementing support for tables
for IPv6. While the IPv6 support in IPFW is generally a bit less  
mature

than IPv4, the one functional thing that is completely missing is
tables. Having them would make my life quite a bit easier. It's the  
one
thing that I have been unable to work around in my dual-stack  
firewalls.

IPFW performance on SMP (vs. PF)

2009-02-11 Thread Oliver Fromme
Hi,

I'll have to implement a packet filter on machines with
several cores (4 to 8).  Which one of the available filters
(IPFW, IPF, PF) will provide the best performance on such
SMP machines?  I heard that PF doesn't support SMP hardware
very well -- is that true?  Will IPFW be better?

Thanks for any insights.

Best regards
   Oliver
