Does Prestige support dynamic IP addressing?
The Prestige supports either a static or dynamic IP address from ISP.
What is the difference between the internal IP and the real IP from my ISP?
Internal IPs is sometimes referred to as virtual IPs. They are a group of up to 255 IPs that are used and
recognized internally on the local area network. They are not intended to be recognized on the Internet. The real
IP from ISP, instead, can be recognized or pinged by another real IP. The Prestige Internet Access Sharing
Router works like an intelligent router that route between the virtual IP and the real IP.
How does e-mail work through the Prestige?
It depends on what kind of IP you have: Static or Dynamic. If your company has a domain name, it means that
you have a static IP address. Suppose your company's e-mail address is [e-mail]. Joe and
Debbie will be able to send e-mail through Prestige Internet Access Device using [e-mail] and
[e-mail] respectively as their e-mail addresses. They will be able to retrieve their individual
private and secure e-mail, if they have been assigned the proper access right.
If your company does not have a domain name, it means that your ISP provides you with a dynamic IP address.
Suppose your company's e-mail address is [e-mail]. Jane and John will be able to send
e-mail through Prestige Internet Access Sharing Router using "jane"<[e-mail]> and
"john"<[e-mail]> respectively as their e-mail addresses. Again, they will be able to retrieve
their individual private and secured e-mail, if they have been assigned the proper access right.
Is it possible to access a server running behind SUA from the outside Internet? If possible,
how?
Yes, it is possible because Prestige delivers the packet to the local server by looking up to a SUA server table.
Therefore, to make a local server accessible to the outside users, the port number and the inside IP address of
the server must be configured in Menu 15 - SUA Server Setup.
What DHCP capability does the Prestige support?
The Prestige supports DHCP client (Ethernet encap) on the WAN port and DHCP server on the LAN port. The
Prestige's DHCP client allows it to get the Internet IP address from ISP automatically if your ISP use DHCP as
a method to assign IP address. The Prestige's internal DHCP server allows it to automatically assign IP and
DNS addresses to the clients on the local LAN.
