7. How do I backup/restore SMT configurations by using TFTP client program via LAN?
a. Use the TELNET client program in your PC to login to your Prestige.
b. Enter CI command 'sys stdio 0' in menu 24.8 to disable console idle timeout.
c. To backup the SMT configurations, use TFTP client program to get file 'rom-0' from the
Prestige.
d. To restore the SMT configurations, use the TFTP client program to put your configuration in file
rom-0 in the Prestige.
8. Why can't I make Telnet to Prestige from WAN?
There are three reasons that Telnet from WAN is blocked.
1. You have disabled Telnet service in Menu 24.11.
Source IP= Telnet host
Destination IP= Prestige's WAN IP
Service= TCP/23
Action=Forward
2. Telnet service is enabled but your host IP is not the securied host entered in Menu 24.11. In this
case, the error message 'Client IP is not allowed!' is appeared on the Telnet screen.
3. The filter rule is applied in the Input Protocol field in menu 11.5 to block Telnet service.
4. The console port is in use.
9. What should I do if I forget the system password?
In case you forget the system password, you need to upload ROMFILE to reset the SMT to factory
default. After uploading ROMFILE, the default system password is '1234'.
10. What is SUA? When should I use SUA?
SUA (Single User Account) is a unique feature supported by Prestige router which allows multiple
people to access Internet concurrently for the cost of a single user account.
When Prestige acting as SUA receives a packet from a local client destined for the outside Internet, it
replaces the source address in the IP packet header with its own address and the source port in the TCP
or UDP header with another value chosen out of a local pool. It then recomputes the appropriate header
checksums and forwards the packet to the Internet as if it is originated from Prestige using the IP address
assigned by ISP. When reply packets from the external Internet are received by Prestige, the original IP
