Virtual Network Mapping
One-to-
One NAT
Every IP Address in the Local Network has a corresponding unique Virtual IP
Address for NAT.
Traffic originating from the Local Network to remote connections will be SNAT’ed
and behave like coming from the defined Virtual Network.
While traffic initiated by remote peers to the Virtual Network will be DNAT’ed
accordingly.
Many-to-
One NAT
The subnet range defined in Local Network will be mapped to a single Virtual IP
Address for NAT. Traffic can only be initiated from local to remote, and these
traffic will be NAT’ed and behaves like coming from the same Virtual IP Address.
DNS Proxy Settings
Enable
To enable the DNS proxy feature, check this box, and then set up the feature
at
Network>LAN>DNS Proxy Settings
.
A DNS proxy server can be enabled to serve DNS requests originating from
LAN/PPTP/SpeedFusionTM peers. Requests are forwarded to the
DNS
servers/resolvers
defined for each WAN connection.
DNS Caching
This field is to enable DNS caching on the built-in DNS proxy server. When the
option is enabled, queried DNS replies will be cached until the records’ TTL
has been reached. This feature can improve DNS response time by storing all
received DNS results for faster DNS lookup. However, it cannot return the
most updated result for frequently updated DNS records. By default,
DNS
Caching
is disabled.
