CLAT
CPE
When the IPv6 only (CLAT) function is enabled, NAT-based functions (like DMZ/Port
Forwarding/Port tigger) cannot be used.
When an IPv4 device accesses the Internet, the performance is degraded because packets need
to be packetized and unpacked. However, IPv6 devices are not affected.
3.8 Multi-APN
The B311-221 supports the establishment and maintenance of three APNs. These three APN
connections isolate data, voice, and remote management services on an operator's network.
The B311-221 supports an independent APN for CPE internal/VoIP/TR-069.
