I've recently purchased Linksys Voice Adaptor SPA-2102 and connected it to my cable modem for VoIP. My phone and internet access both work fine. However, my VPN client can no longer connect to my VPN server at work. Here's how the network looks like - very simple. Cable Modem --> SPA-2102 --> My PC I've tried to get this to work but to no avail. Does anyone know if SPA-2102 even allow VPN to pass through at all? I've played around with the Web-based Configuration but there's nothing on it that would allow me to simply click on a checkbox to allow the VPN to pass through. Am I missing something here? Thanks so much in advance for any information you can provide.
