How To Use The Reset Button; What Is Sua? When Should I Use Sua; Is It Possible To Access A Server Running Behind Sua From The Outside Internet? How Can I Do It - ZyXEL Communications AMG1202-T10B Support Notes

Use the RESET button on the rear panel of AMG1202-T10B/AMG1302-T10B
to reset the router. After the router is reset, the LAN IP address will be reset to
'192.168.1.1', the common user password will be reset to '1234', and the
Administrator password will be reset to '1234'.

4. How to use the Reset button?

a. Turn your AMG1202-T10B/AMG1302-T10Bon. Make sure the POWER
led is on (not blinking)
b. Press the RESET button for longer than one second and shorter than
five seconds and release it.
c. Press the RESET button for six seconds and then release it. If the
POWER LED begins to blink, the default configuration has been
restored and the AMG1202-T10B/AMG1302-T10B restarts.

5. 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 recomputed 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.
6. Is it possible to access a server running behind SUA from the outside
Internet? How can I do it?
Yes, it is possible because AMG1202-T10B/AMG1302-T10B delivers the
packet to the local server by looking up to a SUA server table. Therefore, to
make a local server accessible to the outside users, the port number and the
inside IP address of the server must be configured. (You can configure it in
Web Configurator, Advanced Setup, Network Setting-> NAT -> Port
Forwarding).
