I have tried to get ipfw fwd to work in 6.2-release but it always barfs.

I have recompiled and installed a custom kernel with
options         IPFIREWALL_FORWARD

and I have added to the /etc/sysctl.conf file:
net.inet.ip.forwarding=1

Here's the rule that I'm trying to get to work.

$fwcmd add forward 127.0.0.1,3128 tcp from not me to any 80 in via ${iif}

When I run it I get:

ipfw: getsockopt(IP_FW_ADD): Invalid argument

All the other rules I have work fine.

Am I doing something wrong here?

Anyone else see this behaviour?

TIA,
Terry Todd
