Hello All,
I am new to ipfw. Basically, on my box, i have 3 nics, 1 for external Internet
usage and 2 for internal lan usage : re0, re1. I want to sent ip traffic to
re0, pass it on to ipfw to apply QoS on IP stream and route it through re1 (and
viceversa). I don;t need to have any external IP traffic on re0 and re1. I
tried bridging re0 and re1 which for some unknown reason, only worked for 1 ip
flow, pipe if you will. Thinking, there might be some bridging L2 and ip L3
issues, I am thinking for turning the box into a router, just to forward
packets between re0 and re1 and then apply QoS on it. I am using fixed internal
IP addresses on re0 and re1. I have turned on ip forwarding.
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=18<VLAN_MTU,VLAN_HWTAGGING>
inet 20.20.20.20 netmask 0xffffff00 broadcast 20.20.20.255
ether 00:12:17:55:a4:ec
media: Ethernet autoselect (none)
status: no carrier
re1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=18<VLAN_MTU,VLAN_HWTAGGING>
inet 20.20.20.22 netmask 0xffffff00 broadcast 20.20.20.255
ether 00:12:17:55:a3:fa
media: Ethernet autoselect (none)
status: no carrier
I am don;t understand on how to proceed with set of rules I should be using to
forward ip traffic. Once I have a basic setup that can forward ip, i can then
think of rule set for QoS via pipe and queues. system I will have at least 2
streams of IP traffic via a switch to the freeBSD box. Any help would be
greatly appreciated.
Thanks in advance,
khozaima
