How To Open Port 443 On RedHat 7.1

Hi, I'm running apache on redhat 7.1. When I install the redhat, I customize the firewall configuration to allow incoming on port 80, but I forgot to open port 443. I did ran a probing port test, and I was right. Port 80 is open, and port 443 is closed.

Anybody know how to open port 443 on redhat?

If you're using the built in RH setup for firewall - just type 'setup' at the command prompt and it will have an option for FW config.

Hey, It worked. Thank you.

I have one more question. How can I configure it without going to setup? Is there any other way that is more general to linux? Thanks again.

Yes - if you go back into setup and disable the firewall. The go back to the console - you can use the program ' iptables ' to create your firewall rule set. It's easier to just do a 'man iptables' than for me to try and discuss the syntax.

To other programs you'll want to know about are 'iptables-save' and 'iptables-restore' - because the system will lose your settings after a reboot.

After you're done creating your rule set type 'iptables-save > /etc/firewall.conf' and it will save your configuration to that file in the /etc directory.

Then edit your /etc/rc.d/rc.local file and append 'iptables-restore < /etc/firewall.conf' to the end, which will restore your settings each time upon boot.

At least this is how I do it.. there maybe more than one way to skin a horse, but this works for me.

the file is /etc/sysconfig/iptables

edit the file and when you get it like you want it run this

/etc/rc.d/init.d/iptables restart

try that

also the same command for stop, and start

don't run lokkit or it will rewrite the script.
