Hi. I updated 8 firewalls on NOKIAs IP 330 to IPSO 3.5.1 and CP 4.1 SP5a.

Since then on two of those firewalls I have very strange problem with SMTP packets dropped on RULE 0 with error:

Unknown established TCP packet.

The phoneboy solution didn't help and I really don't know what to do next.

Any ideas ?
