You attempt to telnet to system 192.168.1.240. You receive the following message: "Connecting To 192.168.1.240...Could not open connection to the host, on port 23. No connection could be made because the target machine actively refused it." What may be the problem?
The firewall could be used to protect the network from unauthorised access.Usually an ip could be whitelisted so it could transfer packets between allowing it connect through.
