Summary
When MyPBX locates behind the NAT of a router or a firewall, we need to map ports if we need to visit MyPBX or register extensions remotely. Here is a simple guide for the details.
Ports used in MyPBX by default:
Http blind port: 80(TCP)
SIP port: 5060(UDP)
RTP port range: 10000-12000 (UDP)
SSH port: 8022(TCP)

Note: if TCP/TLS has been enabled for registry remotely, please map these ports too
SIP port via TCP: 5060 (TCP)
SIP port via TLS: 5061 (TCP)
