All Traffic dropped with 'TCP PACKET OUT OF STATE' after NGX61 Upgrade!

[stefan01]

Hi guys,

I have try upgrading SecurePlatform NG R55 to NGX R61 and after the upgrade complete succesfully I have found these following error on all My traffic in SmartView Tracker 'Tcp packet out of state: First packet isn't SYN'
The firewall dropped all traffic and no communication was routed by the firewall...

I have checked with Checkpoint Knowledge base and found nothing about that! Actually I have rolledback to R55 with REVERT process but I want to know why this problem occurs....

Thanks

Just a little Update about this strange problem.

I have built another Checkpoint Firewall LAB to test the upgrade process.

1- Try to upgrade with NGX R60 and everything was working fine after upgrade in my Lab. Traffic is passing through firewall without any problem, no more 'TCP Packet Out Of State'

2- I try to upgrade R60 to R61 and the problem appear again! All traffic is dropped with 'tcp packet out of state' message.

NGX 6.1 seem to have some kind of bug. At this time I will try to upgrade my 'real' Firewall with NGX R60 only.
