P-660R-Tx Series Support Note s
8. The P-660R-Tx supports Bridge and Router mode, what's the difference
between them?
When the ISP limits some specific computers to access Internet that means only
the traffic to/from these computers will be forwarded and the other will be filtered.
In this case, we use bridge mode which works as an ADSL modem to connect to
the ISP. The ISP will generally give one Internet account and limit only one
computer to access the Internet.
For most Internet users having multiple computers want to share an Internet
account for Internet access, they have to add another Internet sharing device, like
a router. In this case, we use the router mode which works as a general Router
plus an ADSL Modem.
9. How do I know I am using PPPoE?
PPPoE requires a user account to login to the provider's server. If you need to
configure a user name and password on your computer to connect to the ISP
you are probably using PPPoE. If you are simply connected to the Internet
when you turn on your computer, you probably are not. You can also check
your ISP or the information sheet given by the ISP. Please choose PPPoE as
the encapsulation type in the P-660R-Tx if the ISP uses PPPoE.
10. Why does my provider use PPPoE?
PPPoE emulates a familiar Dial-Up connection. It allows your ISP to provide
services using their existing network configuration over the broadband
connections. Besides, PPPoE supports a broad range of existing applications
and service including authentication, accounting, secure access and
configuration management.
11. When do I need to choose dynamic IP?
If your ISP provides you an IP address automatically, typically used for Cable
service. In this case your computer gets an IP dynamically assigned by DHCP.
To use this mode, you need to do some corresponding configurations on the
