I have setup an SA520W and configured SSL-VPN for our small business. Everything seemed to go smoothly and I tested SSL VPN by logging in and playing around a bit which seemed to be fine. However, shortly after deployment I started getting complaints about it being much slower than our old VPN through the consumer grade router I just replaced. I investigated and tested with IE8 and Chrome on Windows XP 32-bit with several different machines, and in all instances it did seem very slow indeed. While looking around I noticed that the Task Manager under the Networking tab shows the SSL VPN connection as VirutalPassage at 64 Kbps. Going into Network Connections shows VirtualPassage under the Dial-up heading with device name Virtual Passage SSLDrv Adapter. Additional properties describe it as an ISDN channel. I have attached an image of the Task Manager pane.
The router is running the latest firmware of 2.1.51. It is connected via a static IP that does not require a login, to our dedicated 5 Mbit / 5 Mbit ethernet over copper link to our ISP. We get great speeds and low latency through everything but SSL VPN connections. I haven't done anything fancy so the router certificate is the factory default. Currently we are using the existing 2 SSL VPN licenses that come with the router until we need more access, at which point I want to upgrade to the 25 user bundle. However, I don't feel comfortable upgrading until I get this resolved, because 64kbps simply cannot work for us for a VPN solution.
Does anyone know how to configure the SSL VPN to not limit at 64kbps? My engineers are making fun of me for bringing us back to dialup, and I have to agree with them!
Thanks for any help you can provide!
