Route Table Use this function to enable the Administrator to add static routes for the
networks when the dynamic route is not efficient enough.
DHCP Administrator can configure DHCP (Dynamic Host Configuration Protocol) settings for
the LAN (LAN) network.
Host Table The Bandwidth Manager Administrator may use the Host Table function to make
the Bandwidth Manager act as a DNS Server for the LAN. All DNS requests to a specific
Domain Name will be routed to the Bandwidth Manager’s IP address. The outside Internet
world may access the mail server of the organization easily by its domain name, providing that
the Administrator has set up Virtual Server or Mapped IP settings correctly. However, for the
users in the LAN network, their WAN DNS server will assign them a public IP address for the
mail server. So for the LAN network to access the mail server, they would have to go out to
the Internet, then come back through the Bandwidth Manager to access the mail server.
Essentially, the LAN network is accessing the mail server by a real public IP address, while
the mail server serves their request by a NAT address and not a real one.
