Poor WiFi performance over SonicWall VPN connection in VMware Player on 64-bit Windows 7
Posted on 2013-11-14
I'm thinking the title is a mouthful!! I have a freshly built 64-bit Windows 7 station with 8GB of RAM. I've installed VMware Player 6.0.1. I've installed a 64-bit Windows 7 guest within VMware Player. It's fully patched. It's running MS Security Essentials for AV. Both the host and guest have the Windows Firewall enabled.
Within the guest I've installed the latest SonicWall VPN Client for remote administration. For segregation purposes, I'm trying to keep this particular remote administration separate from the host machine. The guest machine has 4GB of RAM allocated to it. The performance of the guest has been quite good as I've gone through all of the post-installation patching. Downloads have been responsive. Executions have been responsive. I'm able to establish my VPN connection using the SonicWall Client without a problem.
The problems come when I attempt to communicate with the remote network. I can ping no problem and the response is respectable. When I attempt to RDP to a remote server, it bounces back and forth between "initializing remote session" and "securing remote session" several times. Sometimes after 30-60 seconds it will timeout. Other times it will successfully connect and the RDP window opens, but then I don't get any response within the RDP session at all. Even after several minutes, the window will remain open, but no clicks are registered.
I then tried installing the SonicWall VPN Client on the host system as a test. I disconnected the guest station and shut it down. I'm also able to establish the VPN connection from the host station; however, when I then attempt to RDP to the remote server, the response is perfect. It's as though there's packet loss or excessive latency from the VMware Player session. It can't just be WiFi latency through the host station because remember, all of my post-install patching was fine. I downloaded hundreds of gigs of patches and those were fine. It's only when I attempt to communicate over the VPN tunnel that the performance of the remote connections is atrocious.
I've tried turning off firewall both at the guest and host level, but that had no impact. I've tried more memory and less memory for the guest, but that had no impact. I'm not certain what else I can try.
This is a tough one! Any ideas out there?
