Masternode Open Ports

The default firewall policy on my Masternode is to drop all inbound packets, except ports 22, 80, 443 and 9999.

If I run the command "./dash-cli getinfo" with the firewall off I get the required output.

The same command with the firewall on returns the error "couldn't connect to server"

Is there a definite list of ports required for a Masternode?

Many thanks.
 
Masternode actually only needs port 9999. I would suggest closing the others if this is your cool wallet and you have a lot of coins.

dash-cli uses 9998 for rpc port but it should be using localhost by default - make sure you have localhost connections allowed.

22 is for ssh, so if this was a remote one I would definitely keep it open :)
 
Thanks for all the feedback.

I've added port 9998 TCP and UDP. It still doesn't work. If I change the INPUT policy to ACCEPT it works. I haven't specified any restrictions by IP address, these should include localhost?

Any iptable experts?
