How to open ports 53 and 123

[reachmedia]

Hi,

I've checked the following ports, 25, 26, 8006 are open on PMG. However when I tried to do the port testing from my firewall to ports 53 and 123, it indicated as connection refused -> i assumed it is closed.

Is there any way to open it in PMG? I've checked the iptables rules, ufw and did not find anything any rules on it.

Thanks for advising.

By default no firewall rules are configured on a PMG install.
Did you manually configure it?

HI, I did not configure any firewall rules nor install any firewall libraries i.e. iptables or ufw. If that being a case, can I install a CSF firewall in PMG and configure open ports?

If you haven't configured it manually these 2 ports should be open.
How did you test it?

Hi, I've actually run a open port test from my Untangle firewall to port 25, 26, 53, 80, 123, 2703 and 8006.

Only the ports 53 and 123 have refused connection and I've alr open it in my firewall for all local lan interfaces.

Did you install dns server ?
If you did not port 53 will be closed ofcourse

PMG comes without dns server.

You have to install it manually as follow;

apt-get install unbound dnsutils

OK will proceed to install dns server. Are you able to advise on NTP server for port 123?

Thanks

123 is for outgoing traffic. So your machine willl not listen on this port.
Ur server connect ntpd servera for sync ur server time. Remote ntpd will listen from port 123.
