Hi all


We use 2 FWSM version 3.2 (4) in active-failover, transparent, multicontext mode.

I have now a problem with backuptraffic (TCP) between an application server and a backup server through firewall

that traffic hangs after 1,5 hours. In the sniffertrace I see a lot of TCP out-of-order packets.

I have already the TCP state bypass featrure enabled, but without success.

Should I do an ugrade to version  3.2 (5) and activate TCP normalization ?


Thanks for your help.

Regards

Marco
