I have yet to receive any responses to this situation. I surely would
appreciate guidance that anyone may offer. I am hesitant to pursue a
new release, for historically this situation follows uncorrected.

Subject: IPFilter 4.1.13 on Solaris 8
I am attempting to deploy IPFilter 4.1.13 on Solaris 8 systems.
I was unable to deploy IPFilter 4.1.8 due to my trusted computers being
blocked by OOW conditions.
So, I tried IPFilter 4.1.13. Again OOW conditions prevented deployment.
Then I rebuilt IPFilter 4.1.13 with (hopefully) no OOW blocking.
Was:
ip_fil.h:#define FI_OOW 0x0800 /* Out of state window, ... */
Is:
ip_fil.h:#define FI_OOW 0x0000 /* Out of state window, ... */
My logic, though arguably faulty, is that I am apparently living okay
with (alledged) OOW conditions without IPFilter.
I need the protection of IPFilter now.
This modification to IPFilter ran on a test computer for weeks without
any unexpected blocks.
Then when I attempted to deploy it, IPFilter started blocking my
trusted computers. My intent, as shown
by these config statements, is to NEVER block any traffic from any
computers on my subnet
(123.456.78.01 - 123.456.78.99):
pass in quick proto tcp from 123.456.78.0/26 to any flags S keep
pass in quick proto udp from 123.456.78.0/26 to any keep state
pass in quick proto tcp from 123.456.78.64/27 to any flags S keep
state
pass in quick proto udp from 123.456.78.64/27 to any keep state
pass in quick proto tcp from 123.456.78.96/28 to any flags S keep
state
pass in quick proto udp from 123.456.78.96/28 to any keep state
However, as shown below from ipmon logs, sometimes traffic from
123.456.78.xx computers is being blocked.
I hope that someone can see what I am missing.
This situation prohibits me from deploying the much needed IPFilter
firewall.
