Hi
I was trying to use ipfw as a bandwidth emulator. Could anyone please
guide me on how I could use ipfw with bridge enabled.
FreeBSD version: 4.2
FreeBSD is crashing when I try to do the following
I have set the following sysctl variables:
sysctl -w net.link.ether.bridge=1
sysctl -w net.link.ether.bridge_ipfw=1
ipfw add pipe 1 ip allow from any to any in
ipfw pipe 1 config bw 300Kbit/s
ipfw pipe 1 config allow <- it crashes here.
additional info:
I have set following options in my kernel conf file
DUMMYNET
BRIDGE
IPFIREWALL
IPDIVERT
I have the following in my /etc/rc.conf file
firewall_enable = "YES"
firewall_type = "OPEN"
Thanks in Advance
Harish Muppalla
