Step 1:
Set port forwarding in the router for ZX20-A
For the ZX20-A is behind the router, you need forward the IAX2 port in your router, so all
the packets received on the router WAN port (210.11.25.127:4569) will be forwarded to
the ZX20-A (192.168.1.21:4569). Below is the setting page in a linksys router:
Step 2:
Set up the Provider Host in ZX20-B
Set up the service provider and calling rule in ZX20-B to make it register to ZX20-A. This
method is almost the same as above, EXCEPT you need to use the 210.11.25.127 as the
service provider instead of 192.168.1.21.
Step 3:
Set port forwarding in the router for ZX20-B
