I have a server where I need to open incoming ports? I have a mac app with LS 3 on yosmite with an incoming rule that works fine.
allow conections from network :
my process Wired Server
Process owner: me
Port: my port XXXXXX
I made the same rule with LS 4 on sierra , and incoming connections do not work on my server?
where is the difference between LS 3 and 4 ?
Thank you by advance, and sorry I'm french
