How to open port 2195 in iptables CentOS 6 for activating the APNS

Question

I tried this solution:

iptables -I OUTPUT -p tcp --dport 2195 -j ACCEPT
/etc/init.d/iptables stop
/etc/init.d/iptables start

but still can't access the port.

If there are more ports that I have to open for APNS let me know.

How about:

iptables -A INPUT -p tcp --dport 2195 -j ACCEPT
service iptables restart

This may help too.

"iptables -A INPUT -p tcp --dport 2195 -j ACCEPT" There is a extra hyphen in dport. – Patrick Bassut Sep 16 '13 at 04:25

It didn't work for me completely, since my last rule was DROP ALL which basically negated all I added to iptables after.

It might be useful to use the -I switch:

iptables -I INPUT 1 -p tcp --dport 2195 -j ACCEPT

The INPUT 1 - means 1st Input rule instead of appending, to put rule in front of drop all

This fixed my issue - thanks. NOTE: the command ends with the ACCEPT - the 1 following that above is commentary about the '1' that follows the 'INPUT'. – JoeG Jul 25 '18 at 11:14

For CentOS 7, you should use "firewall-cmd" command like so:

firewall-cmd --add-port=2195/tcp --permanent

iptables is not recommended if you use the firewalld service.

Try the following command, it worked for me:

$ sudo iptables -A INPUT -p tcp --jport 2195 -j ACCEPT

$ sudo /etc/init.d/iptables save

/etc command should be executed after executing the before command. – Anjali Bakshi Nov 17 '16 at 13:32
