I am trying to secure my freebsd box and avoid giving to much info away to port scans.
I have found some site relating to this and have put the following lines in /etc/sysctl.conf
and added these to the firewall:
options TCP_DROP_SYNFIN #drop TCP packets with SYN+FIN
Can someone explain to me why the TCP_DROP_SYNFIN option breaks web access? It doesn't seem to have made any changes that I have noticed. I can't find any docs regarding this to explain what it might break. Does anyone know any other variables to add to make me more secure?
Thanks in advance
