When attempting to utilize my work’s VPN client (Dell SonicWALL Global VPN Client) with the Balance 20 (only Mobile Internet, no WAN), I get many failed connections to internal servers (either http or windows network shares). Any connection that does work is painfully slow. Perhaps the failed connections are just timeouts? Not sure, it says net::ERR_CONNECTION_RESET in Chrome.
Pings work perfectly fine and always succeed. All non-VPN connections (even on the same machine) are screaming fast, VOIP is rock solid.
What else can I check and how can I debug this problem?
PS - The problem is nonexistent when connecting my Jetpack directly to my laptop through USB, so I’m fairly confident it’s a router configuration issue.
