SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts over TCP. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. Suppose you wish to build a packet filter rule set allowing inbound and outbound SMTP traffic. You generate the following rule set: Rule Direction Src Addr Dest Addr Protocol Dest Port Action
A In External Internal TCP 25 Permit
B Out Internal External TCP >1023 Permit
C Out Internal External TCP 25 Permit
D In External Internal TCP >1023 Permit
E Either Any Any Any Any Deny

Required:
Describe the effect of each rule.
