Hello, I need to open port 8080, so I added to two IPtables rules: iptables -A INPUT -m state --state NEW -m tcp -p tcp -d remoteserverip --dport 8080 -j ACCEPT iptables -I OUTPUT -p tcp -d remoteserverip --sport 8080 --dport 8080 -j ACCEPT The port still seems to be closed: telnet localhost 8080 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused Please advice . Regards, Shufil

  Shufil, does your WHM server has csf enabled ?

  Which service is running on your 8080 port ? And what is the output of following command ? netstat -apn | grep 8080 iptables -nL | grep 8080

  also i added without -d iptables -A INPUT ( output both udp and tcp ) -m state --state NEW -m udp -p udp --dport 8080 -j ACCEPT so result is iptables -nL | grep 8080 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:8080 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:8080 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:8080 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:8080 Regards, Shufil

  Shufil, what exactly is running on that port? iS the service running? If not telnet would be showing connection refused, as there is nothing running to connect :D

  Hi, You have added correct rule in firewall to open a port 8080 but currently you are not running any services on port 8080 and due to that netstat command is not showing any output.

  Hello :) You will need to ensure a service is listening for connections on port 8080 before it will respond to connection requests. Are you attempting to have a service such as Apache run on port 8080? Thank you.

  shufil , You can configure the ports associated with the service Apache from WHM as follows : Home "Server Configuration "Tweak Settings >> under the section "System"

  HI Triantech , There seems port 80 and 443 in default, if we need to add other port we need to drop 80 or 443 ? Regards, Shufil

  Hello, If you want to make Apache non-SSL connections, drop 80 and add 8080, or the other way around for the SSL connections.

  You can add multiple "Listen" entries in the Apache configuration file. Here is an example of the existing default entries: # grep Listen /usr/local/apache/conf/httpd.conf Listen 0.0.0.0:80 Listen [::]:80 Listen 0.0.0.0:443 Listen [::]:443
  Documentation on making modifications to the Apache configuration file is available here: Custom Directives Outside of a VirtualHost Tag Thank you.
