How to allow port in iptable

Hello,

How to allow port 7777 and 7778 in iptable

 

Check this howto out, it may shed some light

https://help.ubuntu.com/community/IptablesHowTo

 

try
iptables -A FORWARD -p tcp --dport <port number goes here> -j ACCEPT

 

iptables -I INPUT -p tcp --dport 7777 -j ACCEPT
iptables -I INPUT -p tcp --dport 7778 -j ACCEPT

should do it

 

why not use csf or apf firwall.
its easy to specify ports there without complex rules.

 

I tried this iptables -I INPUT -p tcp --dport 7777 -j ACCEPT
iptables -I INPUT -p tcp --dport 7778 -j ACCEPT

But i'm not able to connect to that port an i can only connect when i disable firewal

 

How is your network setup? Is there any router or firewalls in front of your linux box?

Also if you can show the results of /sbin/iptables -L

 

Priority of the rules in the tables plays a role. You need to check on that.

 

iptables -I INPUT -p tcp --dport 7777 -j ACCEPT
iptables -I INPUT -p tcp --dport 7778 -j ACCEPT
iptables save

run it OK. Good Luck
