Mobile Broadband

Traffic Throttling/Shaping on UDP Port 443

Highlighted
2: Seeker

I use VF mobile broadband SIMs in my 4G/LTE router.  Up and down rates are circa 30Mbps.  I can download a 100MB test file (e.g. from https://www.thinkbroadband.com/download) in approximately 15 seconds.
 
However, when I then connect to my company using Cisco Anyconnect on my laptop (using SSL UDP port 443) ...  *** and still via the VF 4G mobile broadband network ***... the same file download takes 10minutes.
 
If I swap the VF SIM with a SIM from a different mobile carrier, the download is again ~15 seconds with (or without) Cisco AnyConnect.
 
This leads me to conclude VF are proactively shaping / throttling traffic using UDP port 443 on their mobile braodband service.
 
Is this expected.
 
My thanks in advance.

Why do you want to use Cisco Anyconnect if the speed is already good without it ?

I'd guess to access equipment located within a secure (ie. private) network!
