Can't access web pages from outside?

[bristr]

Hello, I'm dealing with a strange networking issue. I can't tell if it's Apache or my firewall.
I have a particular server I need to access from outside via web browser. I set up apache to listen on 6571 and I set up port forwarding so when I type domain.com:6571 it should go right to the page. I've done this before without any problems. However, I have a new server that this is not working for. The firewall rule is set up correctly, as I switched the destination to a known good server which worked without any problems. Apache itself is set up to listen on 6571 and I can even access the website internally via that port. This just makes no sense to me.

Thanks in advance.

What does "I can even access the website internally via that port" mean.
Show us the exact URL you are using.

why not start troubleshooting it first internally.

Centos7 uses firewalld (and not iptables - thanks to gerald-clark in recommending firewalld).
First allow port 80 be open in your host machine by:

Code: Select all

firewall-cmd --add-port=80/tcp --permanent

once port 80 is open try to check it using curl or telnet from another machine.

for details see this topic > viewtopic.php?f=51&t=48595#p206437

Opening your webserver to the world would be a quick and easy part.

Have a nice day and happy sharing.

Although the port would be 6571 (not 80)

It turns out the default gateway had not been set up and the server wasn't able to access outside networks. I added the gateway to ifcfg-eth0 and it works now.
Thanks everyone.
