I have a cisco 1710 router running on IOS 12.2something. Using an external modem would it be possible to VPN onto my network via the AUX port? I already have it setup through the ethernet port but the company would like to have dial-up purposes when employees are out of town. I have the necessary hardware and the modem is hooked up. I just wanted to know if anyone has done it before getting to far along with research.
