I use SonicWall VPN Client to connect to my corporate network. Everything works fine when I connect to the Internet
via Ethernet or WiFi connection. Sometimes I need to connect by WWAN - Dell 5550 3G modem. Sonicwall stucks at
"Acquiring IP" - seems like DHCP relaying problem.
I found a troubleshooting document from Sonicwall which describes problems with older Dell WLAN cards. But this is not
an issue. WLAN works fine while WWAN doesn't.
