ETTINGS
UPnP and NAT-PMP are network protocols which allow a computer connected to the
LAN port to automatically configure the router to allow parties on the WAN port to
connect to itself. That way, the process of inbound port forwarding becomes
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 connected to the LAN ports.
When the options are enabled, a table listing all the forwarded ports under these two
protocols can be found at Network>Services>UPnP / NAT-PMP.
18.3.3
Definition of DNS Records
The built-in DNS server functionality of the Peplink Balance facilitates inbound load
balancing. With this functionality, NS/SOA DNS records for a domain name can be
delegated to the Internet IP address(es) of the Peplink Balance. Upon receiving a DNS
query, the Peplink Balance can return (as an “A” record) the IP address for the domain
name on the most appropriate healthy WAN connection. It can also act 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 name www.mycompany.com is delegated to the
WAN2 Internet IP addresses of the Peplink Balance.
Upon receiving the DNS query, the Peplink Balance 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 Peplink Balance are
located at Network>Inbound Access>DNS Settings.
