15.3.2 UPNP / NAT-PMP SETTINGS 
UPnP and NAT-PMP are network protocols which 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' default IP address will be forwarded. 
Check the corresponding box(es) to enable UPnP and/or NAT-PMP. Enable these features only if you 
trust the computers on the LAN. 
 
 
When the options are enabled, a table listing all the forwarded ports under these two protocols can be 
found at Status > UPnP / NAT-PMP. 
 
15.3.3 Definition of DNS Records 
(Available on Peplink Balance 210+) 
The built-in DNS Server functionality of Peplink Balance 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 Peplink Balance. Upon receiving a DNS query, Peplink Balance supports returning, as an 
“A” record, the corresponding 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: 
(This example is for illustration only; the actual resolution that takes place in implementation will likely be 
different.) 
The DNS resolution of the domain namewww.mycompany.comis delegated to the WAN2 Internet IP 
addresses of Peplink Balance. 
Upon receiving the DNS query, Peplink Balance returns, as an “A” record, theIP address for 
www.mycompany.com on WAN1 because WAN1 is the most appropriatehealthy link. 
The settings for definingthe DNS records to be hosted by Peplink Balance are located at:Network> 
Inbound Access > DNS Settings
