DNS Relay
When stabilizing the IP address of a PC connected to the LAN (Home) side, it is necessary to enter
the DNS server address into the PC for it to connect to the Internet. DNS relay shortens this
troublesome process. Due to DNS relay, this product can inform PCs on the LAN (Home) network of
its existence like a DNS server. Regarding DNS inquiries from the LAN (Home) side, this product
contacts a specified DNS server on the WAN (Internet) side, on its behalf. Then it sends the reply back
to PCs on the LAN (Home) side.
The setup page is displayed by clicking DNS Relay.
Note
When connecting a DNS server to the LAN (Home) side, do not use DNS relay.
MTU Size
MTU is the largest possible packet that can be sent. The larger the value of MTU the bigger the packet
can be, which is forwarded in one go. However, if the value of MTU is too big, the packet may be split,
and forwarded in several parts. As a result, the forwarding speed is reduced. Usually, this product sets
an appropriate MTU value automatically. Only modify it when necessary.
The setup page is displayed by clicking (MTU Size).
Note
Data speed may be vastly reduced depending on the MTU settings.
Enable This product sends/receives data to and from PCs on behalf of a
DNS server.

address field.
