You are attempting to implement Client Authentication for FTP. You have the accept firewall
control connection option unchecked in the Policies and Properties dialog box.
In the following Rule base, which rule would prevent a user from performing Client Authentication?
A.
Rule 1
B.
Rule 2
C.
Rule 3
D.
Rule 4
Explanation:
The client authentication will not be performed because rule 1 states that every packet that is
destined to fw.chicago.com will be dropped (without creating a log entry) for any kind of traffic, the
firewall will not accept any connection to it, therefore the authentication request will be dropped
either at port 259 for Telnet or port 900 with HTTP.
Incorrect Answers:
B: This rule provide the authentication.
C: This rule is not related to FTP.
D: This is the clean-up rule, perfectly correct at the end of the rule base.
