i am new to FreeBSD. 
i use freebsd v4.5 Release #0.

i am trying to setup an firewall.
but i couldnt block or pass any IP.
i think i have a mistake about my IPF&IPFW settings.

in my kernel:
options   IPFILTER
options   IPFILTER_LOG
options   IPFIREWALL
options   IPFIREWALL_VERBOSE
options   IPFIREWALL_VERBOSE_LIMIT=10

but my rules doesnt work.
for example:
# ipfw add deny tcp from 193.255.128.250 to any
**answer is:
ipfw: getsockopt(IP_FW_ADD): Protocol not available

when i saw this error i get crazy

Plx help me...
With my best regards.
