You are a network administrator for a WAN that connects two regional insurance company offices—the main office and a satellite office—to each other by a T-3. The main office is also connected to the Internet using a T-3. This T-3 provides Internet access for both offices. To ensure that your private network is not compromised by unauthorized access through the Internet connection, you install a firewall between the main office and the Internet. Shortly thereafter, users in your satellite office complain that they cannot access the file server in the main office, but users in the main office can still access the Internet. What two things should you check?
a. Whether the firewall has been configured to run in promiscuous mode
b. Whether the firewall is placed in the appropriate location on the network
c. Whether the firewall has been configured to allow access from IP addresses in the satellite office
d. Whether the firewall has been configured to receive and transmit UDP-based packets
e. Whether the firewall has been configured to allow Internet access over the main office’s T-3
