Fresh Install Allows All Traffic
Okay, firstly, yes I am new to pfSense but not new to configuring firewalls (although I am certainly not an expert). I have done the due diligence of scouring the internet and forums for any sort of answer to no avail sadly, so here I am.
Perhaps I can start by simply asking the question — does pfSense allow all internet access from a fresh install?
If not, then help me understand why this is true for my situation.
Thank you. So I am not crazy after all.
The short answer is yes, although, more specifically... on a fresh install, PFsense allows all outbound traffic sourced from the subnet assigned to the LAN interface by default. However, there's an implicit deny on all OPT interfaces until firewall rules are added.
