I have a Sonicwall which works with GVC (Global VPN Client) on Windows 7 thru XP perfectly when connected at a hotel or starbucks. But if we have to connect via a Mifi device like Verizon or AT&T provides, then the request for an IP address times out.
When we run a monitor with Sonicwall Support, we can see no traffic on any port where IP address requests are passed. I tried setting up the Mifi unit to allow VPN connectivity since there is a switch for that. but still no good.
Any thoughts? Help? Experience with this?
