Setting Description
Primary/ Secondary
DNS
IP address of the primary and/or secondary DNS are optional as PPPoE will
automatically detect the DNS IP addresses configured at your ISP. However,
if there are other DNS servers you would rather use, enter the IP addresses
in the spaces provided.
MSS Clamping
Click on the “Disable” or “Enable” radio button to disable or enable this option.
MSS (maximum segment size) clamping is used to tell remote networks not
to send packets exceeding the size specified by MTU (maximum
transmission unit) and MSS. For example, the MTU of Ethernet is 1500 bytes
and if you specify 40 bytes for MSS clamping, then you are telling other
networks not to send packets larger than 1460 bytes (i.e. 1500 – 40).
Value
Enter value for MSS clamping if MSS clamping is enabled.
Connection Options
The default setting for this option is “Disable”. You can also select either Dial-
On-Demand or Keep-Alive if desired.
Dial-On-Demand
Enter the inactivity timeout period at which you want to disconnect the Internet
connection when there is no traffic. The minimum value of inactivity timeout is
30 seconds. RIP and SNTP services may interfere with this function if there
are activities from these two services. Make sure that the update interval
setting of the system date and time (in the System Management / Date/Time
Setup configuration page – see 11.4 Setup Date and Time for details) is
greater than the inactivity timeout value.
Keep Alive
Enable this option if you wish to keep your Internet connection active, even
when there is no traffic. Enter the value for the “Echo Interval” at which you
want the RX3041H to send out some data periodically to your ISP. The
default value of “Echo Interval” is 60 second.
