RH9 Firewall blocking webserver

lsgko · 08-16-2003, 05:49 PM

Fresh install of RH9. When I open up mozilla on the machine and type 127.0.0.1 or the machine's ip address, I can see the apache page that cofirms that apache is up and running.

When use the machines ip address on an XP machine connected to the same hub as the linux machine, I get a cannot connect to server. I can ping the linux box successfully from the XP box.

Could this be caused by the firewall on the machine being set incorreclty? If so, where do I go to fix this?

Thanks in Advance.

type iptables -L to list the firewalling rules

using --flush option to remove the firewall
or disable it completely and try again. if it works then obviously its a firewall issue.

It was a firewall issue, I used the flush to get it to work. When I run the "setup" command, I can set the firewall settings, but when ever I go back in to the firewall section it is still set to High.

Where do I go / What command can I use to set the firewall? (Or even better is there a file I can edit to set the firewall settings)

Try setting the input policy to drop:
iptables -P INPUT DROP

Then just allow access to certain ports - eg 80 for http:
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
