Michael,
Depending on the SIP provider and the firewall, you _should_ only need to allow
the signaling traffic of ports 5060 and possibly 5061. The RTP ports should be
negotiated and opened by your Asterisk instance to the SIP provider. If the
firewall doesn't work properly, disable any "sip helpers" as they generally
don't help. You probably also want to have remote access to your SSH port, but
I would change that to something other than port 22. That can be specified in
the user.conf file in /mnt/kd/rc.conf.d/ directory.

Subject: [Astlinux-users] Opening ports
Hi group
I have a customer that will be giving me a public IP e.g. no NAT but wants me
to narrow down my port range to the External interface of the Astlinux box.
What ports do I need to have open? How can I view the open ports on a
production box to see what is open?
Thanks so much.
Regards
Michael Knill
