Its a bridge, right after the router in ingress I;ve tried it different ways, but always 07000 102154250 105301608403 pipe 1 ip from 64.28.67.0/24 to any 07001 81785362 6862740312 pipe 2 ip from any to 64.28.67.0/24 either before or after other rules. (so the rule number changes) the pipes are configured at 80Mbit/s out and 25Mbit/s in (its also a 100Mbit full-duplex line, but we're limiting per cost) ipfw pipe 1 config bw 80Mbit/s delay 2ms ipfw pipe 2 config bw 25Mbit/s delay 2s kernel config has these lines in it: options HZ=20 options DUMMYNET options BRIDGE options NMBCLUSTERS=10240 options IPFIREWALL #firewall options IPFIREWALL_VERBOSE #print information about # dropped packets options IPFIREWALL_FORWARD #enable transparent proxy support options IPFIREWALL_VERBOSE_LIMIT=100 #limit verbosity options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by default options IPV6FIREWALL #firewall for IPv6 options IPV6FIREWALL_VERBOSE options IPV6FIREWALL_VERBOSE_LIMIT=100 options IPV6FIREWALL_DEFAULT_TO_ACCEPT options IPDIVERT #divert sockets options TCPDEBUG version: firewall# uname -a FreeBSD firewall.andover.net 4.2-STABLE FreeBSD 4.2-STABLE #7: Mon Feb 12 08:20:09 EST 2001 root@firewall.andover.net:/usr/src/sys/compile/FIREWALL i386 -trish __ Trish Lynch FreeBSD - The Power to Serve trish@bsdunix.net New England Area BSD Users Group trish@neabug.org Listar Core Committee www.listar.org List Mistress BDSM Community List Project trish@listmistress.org MommaBear @ IRC AilleCat @ Slashdot MommaBearTrish @ AIM http://www.advogato.com/person/AilleCat/ --- "Through the darkness, I would walk the streets, Confessions never seemed to provide me with a release, Held me down and tried to cure me, tried to give me reason, But nothing could separate this burdened mind from me, Here and now, I feel that I'm embracing freedom, Even though I may be alone, but thats ok." -Delerium with Joanna Stevens (Solar Twins), "A Poem for Byzantium" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ipfw" in the body of the message
