4.3.5 Static NAPT Settings
This screen allows you to configure the NAPT (Network Address Port Translation) settings. If the unit is
connected behind a router that uses NAT/NAPT to translate private IP addresses, global IP addresses, VoIP
packets might be blocked by the router, depending on the SIP server. To avoid this problem, this setting is
required. For details, see 1.1.7.2 NAT (Network Address Translation) Setup.
