You may set the iptables/firewall rules to prevent access MONyog except 127.0.0.1.
If you are in Linux you may use the following command to set the iptables rule to block all request other than localhost.
iptables -A INPUT -p tcp –dport 5555 -j DROP
iptables -A INPUT -p tcp –dport 5555 -i lo -j ACCEPT
If you are in windows and if your firewall is enabled you may use the following command.
netsh firewall add portopening TCP 5555 “MONyog” ENABLE CUSTOM 127.0.0.1
If your windows firewall is not enabled you may enable it using the following command
netsh firewall set opmode enable
Please let me know if this solves your problem. If you have any further questions or concerns please let me know.
