Two sets of IPX-2500 behind router
Sometimes the IPX-2500 doesn’t have a public IP address, and you have to configure port mapping for your
router.
Step 1: Configuring the mapping rule of IPX-2500-A on the router.
The IPX-2500-B is connected behind the router, and registers on the IPX-2500-A through Internet. You need
to configure the port mapping of IAX2 port(4569) on the router. Then, all data received from eth0 port of
router(192.168.1.100:4569) will be sent to the IPX-2500-A
Now, take the web management panel of the AND-4100 router as an example.
In here both UTP and TCP must open for IP PBX.
