85
This is the range of IP addresses supplied to incoming callers. This parameter may
require alteration if the default value “10.10.10.0” to “10.10.10.4” does not suit the
remote network configuration.
Mask:
This specifies the IP netmask for the Remote network. This can be used to create a
dynamic route to the remote network whenever the ISDN interface is active.
Primary DNS server:
The answering ISDN interface would normally supply its own PPP IP address to the peer
for DNS requests. This allows you to specify an alternative DNS IP address.
Secondary DNS server:
This parameter can supply a secondary DNS server IP address to the peer for DNS
requests if required.
Enable NAT on this interface
This parameter is used to enable or disable IP Network Address Translation (NAT) on the
answering ISDN interface.
This checkbox opens to show the following options:-
IP Address:
Enable standard Network Address Translation (NAT).
IP address and Port:
Enable Network Address and Port Translation (NAPT).
Enable IPsec on this interface
This parameter is used to enable or disable IPSec processing on the ISDN 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.
This checkbox opens to show the following parameters:-
Keep Security Associations (SAs) when this ISDN interface is disconnected
This checkbox will configure 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 used by IPSec will match that of the Ethernet or
PPP interface specified.
Enable the firewall on this interface
The Firewall parameter is used to enable or disable 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.
To configure the firewall see Configuration > Security > Firewall
