      I have my pfSense configured pretty good…thank you to all on this forum who have help! I really appreciate the help...pfSense rocks!

      How do I know it is secure and private? What are some fundamental checks and tests I can do?

      1. No DNS Leaks/Key traffic thru VPN - All good! used dnsleaktest.com
      2. Fixed IPs for clients/Deny unknown clients - Services->DHCP Server->Interface->Deny Unknown Clients...I think certificates and rRadius can help me further.
      3. pfBlocker with custom lists - More then my share of alerts
      4. Snort - Again more alerts! Constantly being refined
      5. Seperate VLANs - ???
      6. Restricted rules - Thanks all!
        etc...

      My specific questions are:
      a)How can I verify that my VLANs are indeed isolated?
      b)How can I verify my shady printer on VLAN 10(IOT) can't talk to my pfSEnse GUI or my Native VLAN?
      c)My Native VLAN used to admin my AP/Switch/pfSense GUI is not leaking?
      d)My ARP table isn't "poisened"?
      e)My wife is being faithful?....well that one is all on me, you can't help me there!
      f)Other basic trouble shooting/verifications I should do?
      ...what results should I look for to verify all is good in Rome!

      I still have more work to do but any direction/help would be surely appreciated...

        A comprehensive network diagram is worth 10,000 words and 15 conference calls.
        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!
