I am new to IPFilter. My experience comes from other firewalls. I have
what seems like a proper build from following all sorts of example
documents out there. My problem is that nothing seems to pass through
the system. I am not sure if it is a NAT issue or rule misconfiguration
on my part. If someone could critique an excerpt of what I have and clue
me into what I am doing wrong I would certainly appreciate it.
I cut down the rules for simplicity sake. Everything follows:
