So, Not really sure why this happened as it seemed to be working fine.
But, uninstalled then reinstalled pfB.
Deleted all pfB rules on all interfaces that had not been working and set them up one by one.
Now all seems to be working
So a question..
Is there any problem setting up a rule for pfB and then coping to another interface without causing a problem? (Even if copying from a WAN rule to a LAN interface)
I don't think there has been a problem before doing this, but want to verify.
This time around we changed the description on each rule to include the interface name and did not copy rules.
Not sure if this "was" really the fix.
