Failing to get the expected results for the mobile USSD service under WAF !


Hello Everyone,

   Does anyone know if the USSD protocol (Unstructured Supplementary Service Data) can be managed by the F5 WAF to get the expected services?  Even if I have configured a compressive Policy Template with a transparent mode of enforcement but I am unable to get the expected result rather it replies only Ok like the following picture.

Hi @Seid_Huldaro , USSD is supposed to be supported but I saw this protocol a few times only (and very few with ASM). I would suggest to open a support ticket in order to extract some datas from AWAF. 

Feel free to share the support id with me so I can track it. I'm curious to know the outcomes 🙂 

Hello Matthieu_dieric, thank you for your direction and I will share you.
