Hi,

Its is not on Tab smartdefens. Please look under "Web Intelligence"-Tab in
dashboard.  There are a section "http protocol instection". These settings
block your http-traffic..

Best wishes!

Subject: [FW-1] https and Squid

Hi,

I have an Checkpoint Express NGX R60 box running SmartDefense that has just
taked to dropping all https traffic that is handled by our Squid proxy
server which is in a DMZ. The specific SmartDefense error I get in the logs
is: 

Number:         282920
Date:              24Oct2005
Time:             13:44:10
Product:         SmartDefense
Attack Name: Malformed HTTP
Interface:       eth0
Origin:            xxxxlfw01 (192.168.1.5)
Type:             Log
Action:            Reject
Service:         Squid_NTLM (3128)
Source:          xxxxxdc02 (192.168.1.7)
Destination:   xxxxxproxy01 (192.168.252.100)
Protocol:        tcp
Source Port:   1281
Reject ID:       435c588a-4-501a8c0-7b6
Information:   reason: WSE0020001 illegal header format detected: Illegal
start line in request EURL^A^C
                      resource: Unknown

I have been unable to determine exactly which SmartDefense rule is dropping
the packet - I have systematically gone through them and disbaling them
one-by-one hasn't turned up the culprit so I've had to turn SmartDefense (as
a very short-term measure) off to allow https traffic. This may or may not
be relevant - we changed the address (from 192.168.1.254 to 192.168.1.2) of
the firewall object on Saturday which caused some issues with SecureClient.

Can anyone suggest how I resolve this?

Thanks,
Duncan
