3.3.3 Wi-Fi Authentication
The gateway supports the following user authentication protocols for WLAN:
- No encryption
- WEP, WPA2-PSK (AES), WPA/WPA2-PSK (TKIP/AES).
3.4 VPN Function
3.4.1 VPN Client
VPN tunneling involves establishing and maintaining a logical network connection (that may
contain intermediate hops). On this connection, packets constructed in a specific VPN
protocol format are first encapsulated within some other base or carrier protocol, then
transmitted between the VPN client and server, and finally decapsulated on the receiving side.
The B311s-220 supports L2TP and PPTP tunneling protocols.

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 B311s-220 supports the establishment and maintenance of three APNs. These three APN
connections isolate data, and remote management services on an operator's network.
The B311s-220 supports an independent APN for CPE internal/VoIP/TR-069.

4 System Structure and Scenario
Constraints
4.1 System Architecture
Figure 4-1 shows the interfaces for the B311s-220.
Figure 4-1 System structure
The following describes the modules shown in Figure 4-1.
- LTE access function: The B311s-220 adopts the LTE access technology at the WAN side.
- LAN access function: One 10/100/1000 Mbps high-speed Ethernet ports are provided at
the LAN side. The B311s-220 provides the switching function for local networking and
sharing of the broadband network when it is connected to terminal devices.
- AP function: An 802.11b/g/n-compliant WLAN AP interface is provided for wireless
networking at home. The interface is compliant with the IEEE 802.11b/g/n standard and
the WEP, WPA/WPA2-PSK, WPA2-PSK security authentication mechanisms.
- DHCP/DNS: The DHCP server dynamically allocates IP addresses to PCs.
- Web-based management: You can configure the B311s-220 and modify and view the
configuration of the B311s-220.

- IP routing protocol and NAT: The B311s-220 has high-speed routing capability. With the
built-in NAT, the B311s-220, together with LTE terminals, can provide flexible
broadband access solutions and networking schemes.
4.2 Scenario Constraints
The B311s-220 is a household wireless broadband access product designed for use in
scenarios with relatively few network access devices and relatively low network reliability
requirements, such as homes or small office and home offices (SOHOs).
The B311s-220 is not an enterprise-grade product. It cannot be used by medium- or
large-sized enterprises or in scenarios with high network reliability requirements, such as
banks, securities agencies, traffic control, and communications device backhaul.
The B311s-220 has the following constraints:
- When the IP Pass-Through mode is enabled, the HOTA function cannot be used.
- When the L2TP/PPTP VPN client function is enabled, the throughput performance will
slow down.
- A maximum of 32 devices can be connected to the WLAN in theory; the actual number
of devices that can be connected and served depends on actual conditions.
