Appendix F Firewall Security Levels
Custom Security Level
Apply a customized firewall security setting by selecting “Custom” in the Firewall
screen, which lists all services and ports available on the Modem. Services and their
respective ports are open if a check appears in the appropriate check box, or closed
if no check appears. If the service and/or port does not appear in the screen, it is
open. This setting can be modified by clicking in check boxes to open or close par-
ticular services/ports.
