Mobile Network Settings
Enable NAT on this interface
Enables or disables IP Network Address Translation (NAT) on the mobile interface. When
enabled, displays the following options:-
IP Address
Enables standard Network Address Translation (NAT).
IP address and Port
Enables Network Address and Port Translation (NAPT).
Enable IPsec on this interface
Enables or disables IPSec processing on the mobile interface. If enabled, packets sent or
received on this interface must pass through the IPSec code before being transmitted. IPSec
may drop the packet, pass it unchanged, or encrypt and encapsulate within an IPSec packet.
When enabled, displays the following parameters:-
Keep Security Associations (SAs) when this Mobile interface is disconnected
Configures the router to keep any existing IKE and IPsec associations should the link drop. This is
usually applied on head-end routers with fixed IP addresses.
Use interface X, Y for the source IP address of IPsec packets
By default, the source IP address for an IPSec eroute will be the IP address of the interface on
which IPSec was enabled. By setting this parameter to either a PPP or Ethernet interface, the
source IP address IPSec uses will match that of the Ethernet or PPP interface specified.
Enable the firewall on this interface
Enables or disables the firewall script processing for the mobile interface.
Note If the firewall is enabled on an interface and with the absence of any firewall rules, the
default action is to block ALL traffic.
