Dell S2815dn Installation And Configuration Manual page 27

These settings allow the admin to provide additional security by
limiting CACStar admin access to specified IP addresses. If the Allow
all IPs box is checked, an admin can access the CACStar configuration
items from a PC at any IP address if he knows the ID and password.
If it is not checked, the admin must access the CACStar configuration
pages from the IP addresses specified for Administrator #1 or #2.
These addresses must be on the same subnet as the CACStar.
Allow Telnet
If this is enabled CACStar will allow a Telnet session to occur. The
Telnet session will happen over Port 23. Telnet use with CACStar is
intended for diagnostics by the developers.
Allow Non-Secure Port 8080
If this is enabled, CACStar will use Port 8080 and HTTP for HTML.
Otherwise, Port 8443 and HTTPS will be used for HTML. Changing
this setting requires a reboot of CACStar.
Disable Front Panel Configuration
If this is checked, CACStar will disable the Front Panel keyboard from
changing the IP address, subnet mask, and gateway. Viewing of
these settings on the front panel LCD will still be allowed.
SMB Disable NBSS
If this box is checked, CACStar will suppress NBSS traffic from the
printer. This setting is only required when SMB/Kerberos Proxy is
enabled and the local network does not allow NBSS traffic.
