Firewall/Network Service Filter

[randomName]

I'm trying to block a port and it doesn't seem to be working. Is this a bug or can I test it anyway to see if something I'm doing is partially working or completely not?

Thanks

I've used wire shark to find the data to fill in the inputs

you can go here https://www.grc.com/x/ne.dll?bh0bkyd2 and test individual port to see if open or closed/blocked
