I could not have wondered but..Its only me or other people compiling their kernel with this options:
options         KBD_INSTALL_CDEV        # install a CDEV entry in /dev
options         TCP_DROP_SYNFIN         #drop TCP packets with SYN+FIN
options         TCP_RESTRICT_RST        #restrict emission of TCP RST
options         ICMP_BANDLIM                                                   

Those options has any effect? i use them for months but i havent seen any difference between my other machines.

BTW: if i add TCP_DROP_SYNFIN, it should effect setup option in my firewall ?if it is, how ?

Thanks,
