How does the device support TFTP?
In addition to the direct console port connection, the device supports the
uploading/download of the firmware and configuration file using TFTP (Trivial File
Transfer Protocol) over LAN.
Can the device support TFTP over WAN?
Although TFTP should work over WAN as well, it is not recommended because of the
potential data corruption problems.
When do I need NAT?
a. Make local server accessible from outside Internet
When NAT is enabled the local computers are not accessible from outside. You can
use Multi-NAT to make an internal server accessible from outside.
b. Support Non-NAT Friendly Applications
Some servers providing Internet applications such as some mIRC servers do not allow
users to login using the same IP address. Thus, users on the same network cannot
login to the same server simultaneously.
What is BOOTP/DHCP?
BOOTP stands for Bootstrap Protocol. DHCP stands for Dynamic Host Configuration
Protocol. Both are mechanisms to dynamically assign an IP address for a TCP/IP
client by the server. In this case, the device is a BOOTP/DHCP server. Win95 and
WinNT clients use DHCP to request an internal IP address, while WFW and WinSock
clients use BOOTP. TCP/IP clients may specify their own IP or utilize BOOTP/DHCP to
request an IP address.
