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.
3.7 Multi-APN
The B311As-853 supports the establishment and maintenance of two APNs. These two APN
connections isolate data, and remote management services on an operator's network.
The B311As-853 supports an independent APN for CPE internal/TR-069.
