In case you forget the system password, you can erase the current
configuration and restore factory defaults this way:
Use the
RESET button
on the rear panel of P-660R-Tx v2 to reset the router.
After the router is reset, the LAN IP address and the password will be reset to
'192.168.1.1'
and
'1234'
.
7. How to use the Reset button?

P-660R-Tx v2 will reboot.
c. Press the
RESET
button for five seconds and then release it. If the
SYS
LED begins to blink, the defaults have been restored and the Prestige
restarts.
8. 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 source address
and TCP/UDP source port numbers are written into the destination fields of the
packet (since it is now moving in the opposite direction), the checksums are
recomputed, and the packet is delivered to its true destination. This is because
SUA keeps a table of the IP addresses and port numbers of the local systems
currently using it.
