I am trying to add a IPFW rule to forward traffic but I keep
getting the message "ipfw: getsockopt(IP_FW_ADD): Invalid

ipfw add 600 fwd 192.169.2.3, 6000 tcp from 192.169.2.3 to any 80
I do have IP Forwarding enabled. Any ideas what I am doing wrong?
rule looks OK, but your message clearly suggest you DO NOT have IP
forwarding enabled
Interesting sysctl reports that forwarding is enabled:
$ sysctl -a |grep forward
net.inet.ip.forwarding: 1
IP forwarding is enabled in GENERIC isn't it? I am running 6.1-
RELEASE FreeBSD 6.1-RELEASE
I'm looking at a 6.2 box that does forwarding. The GENERIC
kernel does not have this line:
options IPFIREWALL_FORWARD
In my kernel, I am using that. Recollection is you need this
specified explicitly. I could be wrong.
