Is there a way to figure out of my firewall has been tunneled past?

If your firewall has been “tunneled passed” it just means someone has set it so that information can pass though it. The only way to figure out if this has happened is to look at the settings on your firewall.

If you think something happened your best bet is to set your firewall settings back to default so it closes everything and then you have to reopen it as your applications request access.
