Hi

I am pleased to announce the first version of the Packet Filter State
Synchronisation Daemon, called pfsyncd.

It can be found at :

http://www.greyhats.org/openbsd/


Beware : this is an alpha release !
More information is available on the web page.



Enjoy!"
Thanks, jsyn, I had heard some people talking about this but hadn't yet had time to check it out. This looks like pfsync is headed towards real use.

      See this post for a slightly more detailed description of the context.

      I agree, very cool!

        This will let us create multi participant redundant firewalls.

        Whoa. That's wicked cool. I don't have a use for such a thing, but it's still darn savvy.

      So does this just keep the fw's (state and rules) in sync or does it do virtual ip's as well? Am I missing something or.... what good is it to have sync'd fw's if they don't appear to be the same "host", like VRRP?

      This is very cool anyway. :)

        It's funny, I 've built a redundant firewall setup for my company, I've chosen Linux/Iptables because of the stable VRRP implementation of keepalived , but this has the disadvantage that with iptables, you can't share state. Now you can share state on OBSD, but I know of no good VRRP implementation for it!

          Doh! I forgot about that... Screw PF now.. IPTables now officially 0wnz but other than that, I don't know why it 0wnz, just that it does cause I say so!

        maybe the abaility to rate connexions, avoiding some dos attacks (ie: limiting to 10 tcp syn to port 80 / second)...

      I've thought pf better then iptables since 3.1, and that was prior to the nat/pf merger, this was mostly because of the much easier to read syntax.

        pf was better than anything on the planet 1 month into existance.
