Subject: state matching vrs prerouting.... ???

# Experimental UDP Filters
#
# iptables -A INPUT -p udp -i eth0 -m state --state NEW,INVALID -j DROP
# iptables -A INPUT -p udp -i eth0 -m state --state ESTABLISHED,RELATED -j
ACCEPT
# CounterStrike NAT Line
#
iptables -t nat -A PREROUTING -p udp --dport 27015 -i eth0 -j DNAT
--to-destination 192.168.1.25:27015
Ok the UDP filters physically come before my CounterStrike line. In reading
Oskar's tutorial I as under the impression that the nat tables rules took
precedence before the filter tables.... However the UDP rules drop the incoming
CS
requests before they are prerouted... What gives?
