APPENDIX C How to Configure
NAT setting
When MyPBX is behind a NAT(firewall),you need to configure NAT
setting on MyPBX if you want to use a remote extension.
Please follow section 1 or 2 below depending on your network configuration.
1. If MyPBX is connected to a local network, you must set up port forwarding
on your router. Specifically, you must map port 5060 (default SIP port) and
port 10001-10200(default RTP port range) as UDP ports.
Next, log in MyPBX WebGUI, go to „PBX‟->‟Advanced Settings‟ ->‟SIP
Settings‟ -> „NAT‟
External IP Address : your router‟s public IP address

according to your network configuration)
