While trying to debug an issue with intermittent connections to one of the VPN servers, I uninstalled and reinstalled Shrew Soft VPN. ipconfig would show two virtual adapters with the expected IPs. I was able to connect to both at the same time. I am using Shrew Soft VPN to connect to two VPN servers.
