Network requirements
As shown in
, a company uses the private network segment 192.168.1.0/24, and has four
public network addresses: 5.5.5.1, 5.5.5.9, 5.5.5.10, and 5.5.5.11. SIP UA 1 is on the internal network
and SIP UA 2 is on the outside network.
Configure NAT and ALG on the AC so that SIP UA 1 and SIP UA 2 can communicate by using their
aliases. SIP UA 1 selects an IP address from the range 5.5.5.9 to 5.5.5.11 when registering with the SIP
server on the external network.
