APPENDIX C How to configure
NAT setting
When MyPBX is behind a NAT(firewall),you need to configure NAT
setting for MyPBX if you want to use a outernet extension. This is a
STUN like mechanism.
1、If MyPBX are in local network, it means that MyPBX are not in public
network ,you should do port mapping in your router, mapping port 5060 and
10001-10200(RTP port start-RTP port end) as UDP ports mapping.
Then go to MyPBX web interface and do SIP settings as Figure C-1:
Extern IP: your router’s public IP address
Extern Host: your router’s domain
Extern refresh: 20 sec
Local Network Address:192.168.5.0/255.255.255.0 (change this to your
network setting)
NAT mode: yes
Allow RTP Reinvite: no
Figure C-1
Assume that your router’s host address is yeastar.3322.org, your local
network is from 192.168.5.1-192.168.5.254, subnet Mask: 255.255.255.0
MyPBX network setting configured like Figure C-2
