Remove duplicated firewall rules

SimpleFC::AdvAddRule from NSIS Simple Firewall Plugin will add a duplicate rule if the exact rule already exists.

SimpleFC::AdvRemoveRule [name] will remove one entry, but not all of them.

What is a good way to remove duplicated firewall rules?

Solution

  • You could probably use a loop and remove one by one until SimpleFC::AdvExistsRule is false if they all have the same name.
