Advanced Options
Advanced Options
There are two advanced options available, based on the router’s configuration:
Default static route, and Port Address Translation (PAT). If the Static Route
option is not visible in the window, a static route has already been configured on
the router. If the PAT option is not visible, PAT has already been configured on an
interface.

Default Static Route

Check this box if you want to configure a static route to the outside interface to
which outgoing traffic will be routed. If a static route has already been configured
on this router, this box will not appear.
Next Hop Address
If your service provider has given you a next hop IP address to use, enter the IP
address in this field. If you leave this field blank, SDM will use the WAN interface
that you are configuring as the next-hop interface.

Port Address Translation

If devices on the LAN have private addresses, you can allow them to share a single
public IP address. You can ensure that traffic goes to its proper destination by
using PAT, which represents hosts on a LAN with a single IP address and uses
different port numbers to distinguish the hosts. If PAT has already been configured
on an interface, the PAT option will not be visible.
Inside Interface to be Translated
Choose the inside interface connected to the network whose host IP addresses you
want to be translated.
Encapsulation
In this window, select the type of encapsulation that the WAN link will use. Ask
your service provider or network administrator which type of encapsulation is
used for this link. The interface type determines the types of encapsulation
available.
