When setting up Components for agentless monitoring using the AMCE there is a restriction in the UI. You cannot assign a "*" (wildcard, meaning match anything) as the IP address with a given port number, and then use the same port number with a specific IP address in a different component.
Error Title: "Duplicate Protocol", message: "Component <component name> has an overlapping protocol named <protocol> defined with IP address * using port(s) <port number(s)>"
Resolving the problem
There is a reasonably simple workaround that should be effective and manageable in most environments:
Instead of using "*" as the fallback option, try to find out at least the "Class A" IP number. I.e. the first number in the IP address, and make the IP Address "10.*" (substitute 10 for the number in use in that network). Then create another rule with the specific IP - E.g. "10.1.1.1".
