TMOBILE? VPN? Work from home issues

I have the Sagemcom and that explains why it stopped all of a sudden. I contacted my company to ask them to force SSL on Palo Alto GP or allow me to change MTU length in Windows on my laptop, but the admins have to escalate and see if corporate IT security policy will allow it. Who know is that will even fix it. T-mobile needs to get this sorted out because I work from home 2 days a week and a router should be more configurable.
