How to configure PLDT Zyxel P-600 series

I visit a good friend of mine this afternoon because he had a problem with the internet connection in his computer shop. When I got there I see that he is subscribe to PLDT MyDSL, my friend need to established a LAN in his computer shop, since the PLDT modem is capable of being a router I configure it to solve the situation.

I will share to you how I did the configuration of the PLDT Zyxel P-600 series to act as a modem/router.


You may need to set a static IP address on your computer first before you can access the web config. (you know how to do that right?)

computer IP: 192.168.1.100
subnet mask: 255.255.255.0
default gateway: 192.168.1.1

Save settings and reboot.

After restarting, on your web browser type 192.168.1.1

You need to login as admin on your modem to be able to see and make changes to these settings, otherwise you would only see the status page.
If that is the case, then you are logged in only as a guest mode.

Try any of these to login as admin.

for old model black color models:
Username: admin
Password: 1234

or

for newly issued white or red autovolt:
Username: adminpldt
Password: 1234567890

If you entered admin mode correctly, then the password change screen will appear asking you to change the default admin password.

If you click Ignore, this screen will always appear everytime you log in as admin.

It is highly recommended to change the default password.

Click "Go to Advanced setup"

Checked "Click here to always start with the Advanced setup"
If you want to always go directly to advanced setup, otherwise just leave it blank.

This is the status page when in bridge mode... take note of VPI / VCI value here and use it on the next configuration page.

Go to Network / WAN / Internet Connection TAB

Mode: Routing
Encapsulation: ENET ENCAP
Multiplexing: LLC
VPI: 0
VCI: 100

or

VCI: 35

Use whatever VCI works for you.

Then click Obtain an IP Address Automatically

Click Apply

IF unsure about your VPI/VCI settings in your area, call 172 and ask. =D

Go to Network / LAN / IP TAB

IP Address: 192.168.1.1
IP Subnet Mask: 255.255.255.0

Click Apply.

Go to Network / LAN / DHCP Setup TAB

DHCP: Server
IP Pool Starting Address: 192.168.1.100
Pool Size: 32

NOTE: Increase or decrease Pool Size corresponding to your needs.

Click Apply.

OPTIONAL: You can also enter your preferred DNS server if you want.

OpenDNS Servers
Primary: 208.67.222.222
Secondary: 208.67.220.220

Google DNS
Primary: 8.8.8.8
Secondary: 8.8.4.4


Go to Network / NAT / General TAB

Check Active Network Translation (NAT).
Check SUA Only.

Click Apply.

Go to Maintenance / Tools / Restart TAB

Then restart to make the new configuration take effect.

After restarting, you can check the status page of your modem to verify the settings.

The System Status is already in routing mode, and the Device Information now shows your IP address, Subnet Mask, and Default Gateway and the DHCP server is now active.

Above values are just an example, you could set your own values like in IP starting address and pool size, etc.

After this, you can change your computer back to Dynamic IP Address if you like.

If it doesn't work out, try hard resetting your modem, hold the reset switch at the back of your modem for a few seconds then try following the guide again.
