I can ac

Answer 1

Disable SELinux

$ sudo setenforce 0

Answer 2

In case not solved yet. Your iptables say:

state RELATED,ESTABLISHED

Which means that it lets pass only connections already established... that's established by you, not by remote machines. Then you can see exceptions to this in the next rules:

state NEW tcp dpt:ssh

Which counts only for ssh, so you should add a similar rule/line for http, which you can do like this:

state NEW tcp dpt:80

Which you can do like this:

sudo iptables -I INPUT 4 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

(In this case I am choosing to add the new rule in the fourth line)

Remember that after editing the file you should save it like this:

sudo /etc/init.d/iptables save

Answer 3

this would work: -- for REDHAT use : cat "/etc/sysconfig/iptables"

iptables -I  RH-Firewall-1-INPUT -s 192.168.1.3  -p tcp -m tcp --dport 80 -j ACCEPT

followed by

sudo /etc/init.d/iptables save

Answer 4

Try with below setting in iptables.config table

iptables -A INPUT -p tcp --dport 80 -j ACCEPT

Run the below command to restart the iptable service

service iptables restart

change the httpd.config file to

Listen 192.170.2.1:80

re-start the apache.

Try now.

Answer 5

Search for LISTEN directive in the apache config files (httpd.conf, apache2.conf, listen.conf,...) and if you see localhost, or 127.0.0.1, then you need to overwrite with your public ip.

Answer 6

Try disabling iptables: service iptables stop

If this works, enable TCP port 80 to your firewall rules: run system-config-selinux from root, and enable TCP port 80 (HTTP) on your firewall.
