ADTRAN Routers with CradlePoint CBA750B Configuring the ADTRAN Router

ADTRAN Router Sample Configurations for Verizon Dedicated Internet Access

Reference ADTRAN router sample configurations are listed in the following sections. These should be

suitable for providing wireless WAN failover using the CradlePoint CBA750B with Verizon's dedicated

Internet access service. The configurations make a few assumptions that may require modification:

1. The router is not acting as a DHCP server, and thus has DNS proxy disabled.

2. The configuration allows SSH, HTTP, HTTPS and ICMP packets through the firewall. These can be

restricted by modifying the ACLs for additional security.

3. The LAN IP address 10.10.10.1/24 is assigned to the LAN interface. A different subnet can be

substituted.

4. The primary WAN is tracked by sending ping probes to address 4.2.2.2. If a different public address is

required, multiple instances of 4.2.2.2 related to the probe configuration will need modification.

5. The DNS servers are assigned to two public servers 8.8.8.8 and 4.2.2.2. If different DNS servers are

required, the name servers should be modified.

6. Time is requested from the public service, time.nist.gov. If a different server is required, an SNTP

server should be used.
