getsockopt(IP_FW_ADD): Invalid argument

[adnann5]

Hi Guys,

well i've stuck in to something, if any body have any idea please let me know:)

i've configured squid 2.6 stable on freebsd 6.1 and want to make squid work transparently, when i add following into to firewall:

/sbin/ipfw add 10 fwd 127.0.0.1,8080 tcp from 192.168.0.0/24 to any 80

it says following:-

getsockopt(IP_FW_ADD): Invalid argument


how to fix it ? any idea?

Regards

Thanx in advance

Adnan
