Thanks Frank-

I checked those two options, and set them to what you suggested.  No change, the flow rules still do not seem to work.

Anyone else using 2.3RC2 on Solaris 8?

Any thoughts on whether the SUN iPlanet proxy server is disrupting the "flow" of packets?

It appears that none of the flow sigs fire.

Another thing to check is the stream4 and stream4_reassembly
preprocessors. Make sure they are enabled. I highly recommend to use
"ports all" on the reassembler.

My options:
preprocessor stream4: disable_evasion_alerts
preprocessor stream4_reassemble: both, noalerts, ports all

See if that makes a difference.

Regards,
Frank
