Thanks for the research.
Yes I was aware of these settings and tried to add the files you mentioned, but ZA refused to allow me to. Thinking that there must be a special way to do it in ZA was the reason for my post.
I've decided that I'd had enough of ZA. (I'd had other issues in the past), I just uninstalled it completely and installed a new and different Firewall program.
So far everything is working well with Immunet.
Thanks again for your expert help.
