Resolution: To solve this issue, you need to add an exception (or a number of exceptions) into the Windows Firewall configuration.
1. Open the Windows Firewall from the Windows Control Panel.
2. Select the Exceptions tab
3. Press the Add Port.
4. Specify a Name, Port number, and choose the protocol.
Kiwi Syslog Daemon has the ability to also listen on TCP for syslog messages and UDP for SNMP traps.
If you have enabled either of these options from within Kiwi Syslog Daemon, then you will need to create exceptions for each of these as well i.e. if you are listening for port 162.
