DSL-522T ADSL Router User Guide
Description
For PPP connections, a User Name and Password are used to identify and
verify your account to the ISP. Enter the User Name for your ADSL service
account. User names and passwords are case-sensitive, so enter this
information exactly as given to you by your ISP.
Together with the User Name, this is used to verify your account to the ISP.
Enter the Password exactly as given to you by your ISP.
This specifies the protocol (PPPoE or PPPoA) and the encapsulation method
(LLC or VC-Mux) used for your connection. The options available are PPPoE
LLC, PPPoA LLC or PPPoA VC-Mux.
The Maximum Transmission Unit size may be changed if you want to optimize
efficiency for uploading data through the WAN interface. The default setting
(1400 bytes) should be suitable for most users. Some user may want to adjust
the setting to optimize performance for wireless traffic or when low latency is
desired (such as with Internet gaming). It is highly recommended that the user
research how adjusting the MTU may affect network traffic for better or worse.
Similar to the MTU, except this applies to Maximum Received Unit size for
downloading data. Most users will be happy with the default setting (1492
bytes). However this may also be optimized for fast downloads of general bulk
Internet traffic, for low latency or for downloading to computers on the Wireless
LAN. As with the MTU setting, the user should carefully consider how changing
the MRU may affect Internet downloads for all systems on your LAN.
When this is enabled, the Router will be considered to be the primary gateway
to the Internet and WAN for systems on your network. If you are using the
Router on a network with one or more alternative gateway routers, you may
prefer to disable this if you will use another router as the primary gateway.
Network Address Translation may be enabled or disabled with the pull-down
menu. Keep in mind that disabling NAT allows only a single computer to be
used for Internet access through the Router. NAT is enabled and disabled for
the Router on all connections (i.e. Pvc0 – Pvc7) if your Router is set up for
multiple virtual connections.
Use this to universally enable or disable the Firewall and Filter features
available in the Router. If you disable this you will not be able to configure
settings in the Firewall Configuration window or Filters window in the
Advanced directory.
This is used to determine how global IP settings are handled for the WAN
interface. Typically PPPoE or PPPoA connections will use the default setting
for Dynamic IP. Some users will be given a specific IP address for the WAN
interface. In this case you need to change this setting to Static IP. When Static
IP is selected in the IP Control menu, you need to type in the global IP address
provided to you by your ISP. The IP Unnumbered option is used if you want to
set up a non-TCP/IP port protocol link through the WAN interface. An IP
Unnumbered interface does not have an IP address and therefore cannot be
managed via Telnet or any other TCP/IP application.
If you have selected the Static IP option in the IP Control menu, type in the
global IP address used for your WAN interface. Your ISP should provide this IP
address to you.
