P-2024 Support Notes
How does e-mail work through the P-2024?
It depends on what kind of IP address 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 the P-2024 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 rights.
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 the P-2024 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 rights.
What is the difference between the 'Standard' and 'RoadRunner' service?
The
Road Runner
service is commonly used in the USA and it requires the user to "log in" to the service
provider network before Internet access is allowed. The most popular implementation is TAS (Toshiba
Authentication System) with a packet filtering firewall in the upstream direction. Before users are logged in,
they can send ICMP packets (that is, ping) to a remote host through the Internet. However, all outgoing
(upstream) TCP and UDP packets to the Internet are blocked. Thus users can access the local local DNS/login
server. Downstream packets (or packets from the Internet to the users) are not filtered or blocked.
With
Standard
service, no user login is required. This is commonly used with a cable modem. The P-2024
supports both
Road Runner and Standard
services in SMT menu 4 for connecting to the ISPs for Internet
connection.
Is it possible to access a server running behind SUA from the outside Internet? If possible,
how?
Yes, it is possible because P-2024 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 SMT Menu 15 -
SUA Server
Setup.
What DHCP capability does the P-2024 support?
The P-2024 supports DHCP client on the WAN por. The P-2024's DHCP client allows it to get a public WAN
IP address from the ISP automatically if your ISP uses DHCP as a method to assign IP addresses.
