When admin tries to exclude the port in tmproxy, it does not propagate to the 64-bit operating system. Only the 32-bit operating systems accept the exclusion. This is because the exclusion to add it is in the "Wow6432Node" redirection registry.
You may refer to this link to add the commands in IBM fixlet:
- action uses wow64 redirection false
- waithidden regedit /s temp.reg
- action uses wow64 redirection true
After adding the command, the 64-bit operating system will be able to add the exclusion in registry successfully.
