Thought I'd post this up in case anyone here was interested in running a mobile hotspot or having issues with theirs. Recently picked up another hotspot for dmr/dstar mobile use. The plan was to use it in the truck while on the road or on vacation, linked up to an iphone hotspot and using a laptop to toggle between networks/modes in the pi-star dashboard. Verizon apparently didn't think much of my plan, mmdvm connects to the phone but the phone wouldn't assign an ip address for the hotspot or allow traffic. Not an IT guy but I believe they are blocking ports on the phones hotspots to keep traffic down. So what do we do to fix it? Switched my VPN on and it immediately connected up and worked flawlessly. If your having the same problems give a VPN a try, yea it costs a little bit of money but you can use it on your phone and home network.
