Enable NAT on this interface
When checked, this checkbox will enable Network Address Translation to operate on this
interface. This is the same as for other PPP interfaces.
IP address/IP address and Port
These radio buttons select whether IP address translation only should be applied or
whether port number translation should also be applied to IP packets.
Enable IPsec on this interface
When checked, this checkbox will cause the router to encrypt traffic on this interface using
the IPsec protocol. The following two additional configuration parameters are revealed when
this box is checked.
Keep Security Associations (SAs) when this PSTN interface is disconnected
When checked, this checkbox causes the router to maintain (i.e. not flush) the SA when
the interface becomes disconnected. The normal behaviour is to remove the SAs when
the interface becomes disconnected.
Use interface x,y for the source IP address of IPsec packets
If it is required to use another interface (i.e. not the interface currently being configured)
as the source address for IPsec packets, this may be achieved by selecting the desired
interface from the drop-down list and typing the desired interface instance number into
the adjacent text box.
Enable the firewall on this interface
When checked, this checkbox applies the firewall rules to traffic using this interface.
