Stealth Interface Examples

For stealth interfaces, you can select the registered addresses from the list of unused addresses on the network that the Screen segments. In this case, Screen simulates the virtual addresses and responds to ARP requests for those addresses. Since you are not adding additional networks, no routing changes are required.

For example, consider a SunScreen with stealth interfaces that segments the network 199.190.177.0 (netmask 255.255.255.0). In this example, the addresses 199.190.177.100 through 199.190.177.254 are unused and can be used as virtual addresses in network address translations.

For stealth interfaces, you can select the registered addresses from a new virtual network you create. For this to work successfully, you must be able to assign multiple addresses on multiple networks on the routers you use.
