The config below will give mail a lower priority to all of the other traffic, both in and out. Nat interactive addresses? Hmmm... you mean you want ipfw to forward local addresses using nat? you want to dole out local ip addresses, dhcp? Not really sure of the question here, but I'm sure its answered by following the link below to the freebsd handbook. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/index.html # This is a ruleset that will give mail a lower priority to all other packets.

The FreeBSD machine with ipfw is routing and filtering. I need limit and weight data flow, i.e. if interactive session exists, I need fixed bandwidth and asap processing. Batch jobs, like SMTP maybe postponed and processed, if the bandwidth is free. In addition, I need NAT `interactive' addresses. Could anybody point me to a working example? Everything I find is too general or briefly described. Thank you very much in advance.
