Select this option to enable traffic shaper for outgoing traffic. Type
a rate (in kilobits/second) slightly lower than
maximum measured upstream speed of your Internet
connection,
in the field provided.
Try different rates in order to determine which one provides the
best results.
For information on using traffic shaper, see
on page 117.
Select this option to enable Traffic Shaper for incoming traffic.
Then type a rate (in kilobits/second) slightly lower than
the maximum measured downstream speed of your Internet
connection.
You may 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 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,
on page 117.
If you are using High Availability, select this option to configure
WAN high availability. The gateway connects to the Internet only if
it is the active gateway in the high availability cluster.
This field is only enabled if high availability is configured.
For information on high availability, see
157.
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
need not enter this value unless specified by your ISP.
This field allows you to control the maximum transmission unit
size.
As a general recommendation you should leave this
field empty. To modify the default MTU value, it is recommended
that you consult with your ISP first and use MTU values between
1300 and 1500.
