16. The Router will save the new settings and restart. Upon restarting the Router will automatically establish the WAN 

connection. 

Additional settings for PPPoE/PPPoA connections: 

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 effect 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
