ZyWALL 35 Support Notes

A12. How does e-mail work through the ZyWALL?

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 ZyWALL 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 ZyWALL 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.
A13. Is it possible to access a server running behind NAT from the outside Internet? If
possible, how?
Yes, it is possible because ZyWALL delivers the packet to the local server by looking up to a NAT server
table. Therefore, to make a local server accessible to the outsider, the port number and the internal IP
address of the server must be configured in NAT menu.

A14. What DHCP capability does the ZyWALL support?

The ZyWALL supports DHCP client on the WAN port and DHCP server on the LAN port. The
ZyWALL's DHCP client allows it to get the Internet IP address from ISP automatically. The ZyWALL's
DHCP server allows it to automatically assign IP and DNS addresses to the clients on the local LAN.

A15. What are the capability of wireless feature of ZyWALL

Wireless in ZyWALL series support embedded 802.1x MD5/CHAP authentication of 32 clients.

A16. What is the coverage range of Wireless in ZyWALL?

The coverage range typically is 50m~80m indoor, 150m~300m outdoor. The actual range may very depend on
environment, as to obstacles and walls, RF interference, in the environment.
