AT&T Wireless Devices cannot connect to Sonicwall VPN
I have approximately 28 wireless mobile devices and hotspots on a business plan that can connect to the internet, but are unable to connect to our VPN (Sonicwall client). I have also confirmed this is an issue on my personal AT&T device. We have user's that also have personal Verizon and Sprint devices, and user's are able to connect to the VPN on those. I've contacted Sonicwall, and they say it is an issue with the Wireless provider. Has anyone else encountered this issue? This appears to have originated about a month ago.
