A ScreenOS firewall has one interface in the user zone and one interface in the servers
zone. Both interfaces are addressed and active. The configured policy allows user traffic
from the user zone to the FTP server in the servers zone, but the traffic does not cross the
firewall from the client to the server. What is the most likely problem with the firewall?

A.
The ScreenOS firewall has no physical connection to the FTP server.

B.
The ALG option on the ScreenOS firewall has not been enabled for FTP traffic.

C.
The ScreenOS firewall does not have a route defined to the FTP server’s subnet.

D.
The ScreenOS firewall does not have a route defined to the FTP client’s subnet.
