ipfilter keep state bug

Hi all,
Just to feedback that I'm still experiencing the "keep state" bug
filed at http://mail-index.netbsd.org/netbsd-...0/06/0004.html

I'm using ip_fil4.1.13.tar.gz on a Solaris 8. Instead of netbsd in the
bug report above, the nfs clients I experienced the bug on are redhat
9.0 and RHEL ES release 3.

If I commented out the below line (useful for web surfing), the nfs
problem is solved:

pass out quick on eri0 proto tcp/udp from any to any keep state

Otherwise, although the nfs client and mount the exported directories
on the Solaris nfs server, reading the mounted files on the nfs client
just hangs there.

Regards,
KL
