Hello Heiko, 

       I am looking for documentation for F5 LTM i2600 integration with Sandblast appliance. Do you have one? 

Thank you!

Regards,

Coco

Hi Coco,

On F5 side this is a bit problematic. You can't limit the number of ICAP sessions. For example, if the TE appliance is set to 100 sessions and you open the 101 session, you will get an ICAP error.

Unfortunately, this cannot be adjusted on the F5 side. I have already opened a ticket at F5. But so far without success.

On the TE Appliance you have to configure it as described in my articles:

Symantec (Bluecoat) SG ICAP and Sandblast (TEX) 

Fortigate Firewall ICAP and Sandblast (TEX) 

Here you can find an article how it works with F5:

AskF5 | Manual Chapter: Configuring Content Adaptation for HTTP Requests 

Regards

Heiko

Thank you for the sharing Heiko!

In my design, customer will have F5 LTM work with 2-3 Sandblast appliances. In this case, will LTM be able to deliver the 101 session to next available Sandblast appliance? Thank you!

Regards,

Coco

Hi Coco,

it is the same issue! The problem is only shifted (100* 3 Te appliances). So you have the ICAP error of the 301 connection. With Bluecoat or Fortigate you can define the upper limit "max ICAP connections". With F5 this is unfortunately not possible. This means that this can always be a problem if it is exceeded. I have not found a solution yet. 

Regards,

Heiko

Thank you so much.

Sorry, I have no experience with R80.20 and ICAP yet.

I'll try that out in the next few days.
