Better VPN performance for VMWare

[solignis]

Hi, I was wondering if there is anything I can do to make my VPN more efficient for my VMWare admin software.

What I mean is the VMWare vSphere client has a lot of lag in it and I want to know what I can do to my VPN to reduce some of the lag is the system.

I am running OpenVPN 2.1RC19 on Windows XP w/SP3 for my server, and my only client at the moment is a Vista Ultimate x64 SP2 with the same version of OpenVPN as the server.

As an attempt to improve performance I tried switching to TCP, that seemed to help a little bit even despite the overhead it generates. I added a QOS rule to my firewall also, and I switched from AES 128 to Blowfish. I was always told that blowfish is a little bit "lighter weight" than AES or 3DES.

Is there anything else I can do or something I should not have done?

I would recommend not using TCP for the VPN if you can help it. As you've already indicated you're aware, there is a considerable amount of overhead added when one is tunneling TCP within TCP.

One thing you may be able to do is run the MTU test. Simply add --mtu-test to the command options and the logs will indicated an optimal MTU setting. From there, there is not much more you can do.

How to find out if a VPN 3000 Series Concentrator has been configed correctly? This is my first time working on a VPN 3000 Series Concentrator and im trying to see if it configed correctly but no really sure how to find out if it is or not, plus I'm wanting to create redundant VPNs if the main VPN for one site goes down, another concentrator will pick up that down VPN and bring it back up.
