We're running Solaris 10U8, with the latest ipfilter patch. We're having a
problem where inbound connections that should be allowed by a stateful rule
are being dropped.

For example:

Apr 12 16:31:53 kyle ipmon[117]: [ID 702911 local0.warning] 16:31:53.771244
e1000g0 @20:10 b 134.71.247.49,712 -> 134.71.247.14,2049 PR tcp len 20 60
-S IN

This blocked SYN packet shows it was blocked by rule 20:10:

@10 pass in quick proto tcp from 134.71.0.0/16 to any port = nfsd flags
S/SA keep state group 20

What does the head rule for group 20 look like? Is it quick also? If not, try setting quick on the head rule as well. I seem to recall seeing odd behavior if the head and the group don't agree on quickness.
