Very basic question

[kareen]

Dear Forum,

Hello and I am new to this Forum and PFSense.
I have a very general question. :-[

I installed PFSense on my PC.
Is there some basic protection already working ? ..and could you recommend some
documents with some basic rules for protecting my internal network?

Thank you for any suggestions!

Incoming traffic on WAN is blocked by default.  LAN is wide open.  Any extra interfaces like OPT1 will have to have at least one rule added to allow access out.
