put firewall files in /etc/firewall

Add to /etc/rc.d/rc.local

#RUN REBBYs FIREWALL
/etc/firewall/rFW -start


Some controls like this are good:

echo 0 > /proc/sys/net/ipv4/tcp_syncookies

echo 131072 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
echo 32768 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 16384 > /proc/sys/net/ipv4/neigh/default/gc_thresh1

echo 2048 > /proc/sys/net/ipv4/tcp_max_syn_backlog
echo 65536 > /proc/sys/net/ipv4/route/gc_thresh

echo 655280 > /proc/sys/net/ipv4/netfilter/ip_conntrack_max
#echo 1 > /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_be_liberal 
echo 172800 > /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_timeout_established
