Configuring a Remotely Controlled NAT Pool

Step-by-Step Procedure

To configure a remotely-controlled NAT pool:

Create a NAT pool, and specify a name for the pool.[edit services] user@host#edit nat pool pgcp-pool
Configure an address range for the pool.[edit services nat pool pgcp-pool] user@host#set address-range low 10.10.20.100 high 10.10.30.100
Configure a range of ports. If you configure the NAT pool as remotely controlled, you must set a specific port range rather than using an automatic assignment of ports.[edit services nat pool pgcp-pool] user@host#set port range low 10000 high 50000
Specify that the NAT pool is used exclusively by the packet gateway. [edit services nat pool pgcp-pool] user@host#set pgcp
Specify that the PGC controls the addresses and ports in a NAT pool. The PGC reserves the addresses and ports when it requests specific local NAT bindings for remote addresses. (By default, the PG controls the addresses and ports in a pool.)[edit services nat pool pgcp-pool] user@host#set pgcp remotely-controlled
Configure the number of ports allocated to voice and video flows on the MultiServices PIC. This value is useful when one port is allocated for Real-Time Transport Protocol (RTP), and the accompanying Real-Time Control Protocol (RTCP) flow uses the other port. By default, 2 ports are available. To support the extra ports required for combined voice and video flows, you can specify 4 ports.[edit services nat pool pgcp-pool] user@host#set pgcp ports-per-session 4
