Prestige 2301R/RL-P1C Support Notes

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 ZyXEL device 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 xxx@mycompany.com. Joe and Debbie will be able to send e-mail through Prestige Internet Access Sharing Router using jane@mycompany.com and debbie@mycompany.com 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 mycompany@ispname.com. Jane and John will be able to send e-mail through Prestige Internet Access Sharing Router using "jane"<mycompany@ispname.com> and "john"<mycompany@ispname.com> 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.

What is the difference between the 'Standard' and 'RoadRunner' service?

The US Road Runner service requires the user to "log in" to the service before it can send any packets to the outside network. This is apparently implemented in the TAS (Toshiba Authentication System) with a packet filtering firewall in the upstream direction. Before login, one can send ICMP packets (e.g., ping) to the outside Internet, but nearly all other upstream TCP and UDP packets are blocked. The user can only speak to the local DNS/login server. Downstream packets do not appear to be filtered or blocked at any time.

While Standard service means the cable services which have no login requirement. Prestige supports both Road Runner & Standard services in menu 4 for connecting to cable ISPs.
