2. Click the

3. In the Profile name field, enter a name for the profile. This name is only used to identify the profile on the router.
4. Ensure that the
Automatic APN selection
toggle key is set to off. If it is not, click it to toggle it to the off position.
5. In the
APN
field, enter the APN Name (Access Point Name) and if required, use the
Username
and
Password
fields to enter your login credentials.
6. Next to Authentication type, select the either CHAP or PAP depending on the type of authentication used by your provider.
7. The
Reconnect delay
field specifies the number of seconds to wait between connection attempts. The default setting of 30 seconds is sufficient in most cases but you may modify it
to wait up to 65535 seconds if you wish.
8. The
Reconnect retries
field specifies the number of times to attempt to connect to the network if the router fails to establish a connection. It is set to 0 by default which causes the
router to attempt to reconnect indefinitely.
9. The
Metric
value is used by router to prioritise routes (if multiple are available) and is set to 20 by default. This value is sufficient in most cases but you may modify it if you are
aware of the effect your changes will have on the service.
10. The MTU field allows you to modify the Maximum Transmission Unit used on the connection. Do not change this unless instructed to by your carrier.
11. Use the
NAT Masquerading
toggle key to turn NAT Masquerading on or off. NAT masquerading, also known simply as NAT is a common routing feature which allows multiple LAN
devices to appear as a single WAN IP via network address translation. In this mode, the router modifies network traffic sent and received to inform remote computers on the internet
that packets originating from a machine behind the router actually originated from the WAN IP address of the router’s internal NAT IP address. This may be disabled if a framed
route configuration is required and local devices require WAN IP addresses.
12. For advanced networking such as using dual simultaneous PDP contexts, you may wish to configure a particular profile to route only certain traffic via that profile by configuring a
custom address and mask of traffic to send via that profile. To do this, in the Profile routing settings section, enter the
Network address
and
Network mask
of the remote network. If
you do not want to use this feature, or are unsure, please leave these fields blank, which will not designate any particular traffic to be routed via this profile. For more information on
configuring Profile routing settings, see the
Setting a default gateway with two active connection profiles example.
