dialog for a new access rule entry.

How Do I Configure NAT on an Unsupported Interface?
SDM can configure Network Address Translation (NAT) on an interface type
unsupported by SDM. Before you can configure the firewall, you must first use
the router CLI to configure the interface. The interface must have, at a minimum,
an IP address configured, and it must be working. To verify that the connection is
working, verify that the interface status is Up.
After you have configured the unsupported interface using the CLI, yo u can
configure NAT . The unsupported interface will appear as Other on the router
interface list.
