Resetting The Zywall To Its Factory Defaults; Packet Flow - ZyXEL Communications ZYWALL P1 User Manual

• If the sites are/were previously connected using a leased line or ISDN router, physically
disconnect these devices from the network before testing your new VPN connection. The
old route may have been learnt by RIP and would take priority over the new VPN
connection.
• To test whether or not a tunnel is working, ping from a computer at one site to a computer
at the other.
Before doing so, ensure that both computers have Internet access (through the IPSec
routers).
• You can use the "E-MAIL" Peer Type and the "SUBNET" Local and Remote Address
Type to simplify the configuration.
• Do not manually create any static IP routes for the remote VPN site. They are not required.

25.6 Resetting the ZyWALL to Its Factory Defaults

If you forget your password or cannot access the web configurator, you will need to use the
RESET button on the back of the ZyWALL. If you reset the ZyWALL, you lose all of the
changes you have made. The ZyWALL re-loads its default settings, and the password resets to
1234. You have to make all of your changes again.
You will lose all of your changes when you push the RESET button.
Make sure the PWR LED is on (not blinking) before you begin this procedure.
1 Press the RESET button in for about 10 seconds and release it. When the PWR LED
starts to blink, the defaults have been restored and the ZyWALL restarts. If this does not
restore the defaults, go to step 2.
2 Disconnect the ZyWALL's power.
3 While pressing the RESET button, reconnect the ZyWALL's power.
4 Continue to hold the RESET button. The PWR LED will begin to blink. This indicates
that the defaults have been restored. Release the RESET button.
5 Wait for the ZyWALL to finish restarting before accessing again.
