Downstream: Link
Rate
Select this option to enable Traffic Shaper for incoming traffic. Then type a
rate (in kilobits/second) slightly lower than your Internet connection's
maximum measured downstream speed in the field provided.
It is recommended to try different rates in order to determine which one
provides the best results.
Note: Traffic Shaper cannot control the number or type of packets it
receives from the Internet; it can only affect the rate of incoming traffic by
dropping received packets. This makes the shaping of inbound traffic less
accurate than the shaping of outbound traffic. It is therefore recommended
to enable traffic shaping for incoming traffic only if necessary.
For information on using Traffic Shaper, see Using Traffic Shaper on
page 293.
Advanced
External IP If you selected PPTP, type the IP address of the PPTP client as given by
your ISP.
If you selected PPPoE, this field is optional, and you do not have to fill it in
unless your ISP has instructed you to do so.
MTU This field allows you to control the maximum transmission unit size.
As a general recommendation you should leave this field empty. If
however you wish to modify the default MTU, it is recommended that you
consult with your ISP first and use MTU values between 1300 and 1500.
MAC Cloning A MAC address is a 12-digit identifier assigned to every network device. If
your ISP restricts connections to specific, recognized MAC addresses, you
must select this option to clone a MAC address.
