3.2. Restrictions
Access restriction
VN-E4 comes with a feature that enables it to deny access from a specific IP address. If access from the IP address of the client is denied,
VN-E4 will disconnect the TCP connection immediately after TCP is connected via the port number 32040.
Maximum number of clients
The maximum number of clients that may acquire alarm is 4. When a 5th client sends a SYN for TCP connection to port number 32040,
VN-E4 will return an RST.
Additionally, VN-E4 will also check whether the TCP connection is maintained at regular intervals. VN-E4 will disconnect the TCP
connection if syn exchange is not performed in 10 minutes.
