UPnP/NAT-PMP Settings
Universal Plug and Play (UPnP) and NAT Port Mapping Protocol (NAT-PMP) are network protocols that
allow a computer on the LAN to automatically configure the router to allow parties on the WAN to connect to
itself. In this way, the process of inbound port forwarding is automated.
When a computer creates a rule using these protocols, the specified TCP/UDP port of all WAN connections of
the default IP address will be forwarded.
Check the corresponding box(es) to enable UPnP and/or NAT-PMP. Only enable these features if you trust
the computers on the LAN.

When enabled, click on

or NAT-PMP.
DNS Records
The built-in DNS Server functionality of the BD1000 facilitates inbound load balancing. With the presence
of the functionality, NS/SOA DNS records for a domain name can be delegated to Internet IP address(es) of
the BD1000. Upon receiving a DNS query, the BD1000 supports returning, as an “A” record, the corre-
sponding IP address for the domain name on the most appropriate healthy WAN connection. It also supports
acting as a generic DNS server for hosting “A,” “CNAME,” “MX,” “TXT” and “NS” records.
For example (for illustration only; the actual resolution that takes place in implementation will likely vary):
The DNS resolution of the domain name www.mycompany.com is delegated to the WAN2 Internet IP
addresses of the BD1000. Upon receiving the DNS query, the BD1000 returns, as an “A” record, the IP
address for www.mycompany.com on WAN1 because WAN1 is the most appropriate healthy link.
The settings for defining the DNS records to be hosted by the BD1000 are located at:
