Hi,

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.

If your Sonicwall is trying to acquire an IP address from DHCP server on the remote side, it means that VPN connection was already established.
Sounds like your firewall is not allowing this to happen. Turn off any Symantec, NOD32 or other firewall/security software installed.

I finally found a solution - the problem was with driver versions. NDIS was incompatible with SonicWall VPN client. It revealed that the client is a very old version. I upgraded Sonicwall client and problem dissapeared.

The problem was with Drivers / NDIS not firewall / AV.

NDIS is an application programming interface (API) for network interface cards (NICs).

Firewall is designed to work with network cards using API.
