Hi,

Good day!

Hopefully we could hasten the solution for this issue as this is one of the main problems on each and every firewall/UTM firewall/Next Generation firewall today. Any work around?

Warm Regards,
Deo

Hi,

Possible workaround is that you may capture packets from the NGAF UI, then further analyze from the packet, and then custom an application or URL to block it.

Hi @deoangelolim

For Ultrasur
--------------
you can enable or disable it by going to
navigation area, choose Objects>Intelligent Ident DB. The Intelligent Ident Data base page is displayed on the right.
Select ultrasurf and enable or disable it.

For  Psiphon

The only way to block all proxy to create rule in firewall to reject all ports, and create rule in web protection to block all categories but this is not a solution !!

Hi Aadreenbutt,

Good day!

Blocking all ports is not impossible but it is so hard as ports always changes. I have tried this for several times blocking almost a hundred ports.

Warm Regards,
Deo
