A18. What network interface does the new ZyWALL series support?
The new ZyWALL series support auto MDX/MDIX 10/100M Ethernet LAN/WAN port to connect to the
computer on LAN and 10/100M Ethernet to connect to the external cable or xDSL modem on WAN.
A19. How does the ZyWALL support TFTP?
In addition to the direct console port connection, the ZyWALL supports the uploading/download of the
firmware and configuration file using TFTP (Trivial File Transfer Protocol) over LAN.

A20. Can the ZyWALL support TFTP over WAN?

Although TFTP should work over WAN as well, it is not recommended because of the potential data corruption
problems.

A21. How can I upload data to outside Internet over the one-way cable?

A workaround is to use an alternate path for your upstream path, such as a dial-up connection to an Internet
service provider. So, if you can find another way to get your upstream packets to the Internet you will still be
able to receive downstream packets via ZyWALL.
A22. My ZyWALL can not get an IP address from the ISP to connect to the Internet, what
can I do?
Currently, there are various ways that ISPs control their users. That is, the WAN IP is provided only when the
user is checked as an authorized user. The ISPs currently use three ways:
1. Check if the 'MAC address' is valid
2. Check if the 'Host Name' is valid, e.g., @home
