This is related to my previous question. Not really a need to read it, but I'm running a Fedora 15 webserver and I've been trying to get Apache running correctly.
I've got an incorrectly configured firewall for a webserver at the moment - it's blocking inbound requests on port 80. I found it was a problem with iptables, so ran a command to correct it:
/sbin/iptables -A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT
That didn't do anything. Both before and after I restarted the iptables service, I got no response from the server.
The next suggestion on the page I'm using to fix this is to append these lines to /etc/system/iptables, so I tried that:
-A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 443 -j ACCEPT
But iptables wouldn't even start after I added these lines. so I changed them to look more like the rest of my config file. So now the file in its entirety looks like this:
# Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT
The lines I added are the ones separated in the middle. Alas, this didn't work either. And I am making sure to restart the iptables service after each thing I try.
So, how could I fix this to allow my webserver to act correctly, being able to serve websites on port 80 (and 443)? I do need to leave iptables enabled, right?
