IPS dropping legitimate traffic

Hi Everyone,

 

I hope you can help me out sorting this one out, basically we have some VPN users that are trying to access a SQL database via MySQL Workbench and the IPS is for some reason dropping the traffic, from the debugs this is what I can see:

 

@;184396671;[cpu_2];[fw4_1];fw_log_drop_ex: Packet proto=6 10.203.125.10:19993 -> 10.88.23.34:3306 dropped by fwpslglue_chain Reason: PSL Reject: INSPECT_STREAMING_0;

 

However I have been unable to find much information in regards to the drop reason.

 

Have you ever seen something like that or know what may be causing it?

 

Thanks in advanced for the assistance provided.

1) Use an IPS exception rule to allow the traffic for the IP (MySQL Server).

If this does not help, you can disable passive streaming (PSLXL) in SecureXL path  for the IP with fast acceleration.

2) The fast acceleration feature lets you define trusted connections to allow bypassing deep packet inspection on R80.20 JHF103 and above gateways. This feature significantly improves throughput for these trusted high volume connections and reduces CPU consumption.

Hi Heiko,

 

Ideally I would want to avoid IPS exception as the source is all our VPN pool and the destination is our SQL databases so we would leave our SQL databases without IPS protection against VPN users.
