Trying to figure out why, when I enable the firewall on my cisco (which is a state checking firewall) and I have my iptables (also state checking) firewall enabled on my redhat box I can not establish a connection with with my website (either website one as I have two interfaces and I am using apache to host both) It almost seems as if the cisco is destroying the incoming connection (probably the outgoing response because I can see people connecting to my box) before my box has a chance to send out a response. If I run no firewall on my redhat box and leave the firewall up on my cisco then you can access my website normally. If anyone has had this problem please let me know. FYI, my simple firewall test: F1="eth0" IF2="eth1" IP2="xxx" #(real ip address hidden) IP1="xxx" #(real ip address hidden) UNPRIVPORTS="1024:65535" iptables -F iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT DROP iptables -A INPUT -p tcp --sport $UNPRIVPORTS \ --dport 80 -m state --state NEW -j ACCEPT iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A OUTPUT -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT Many thanks, Justin
