I can't get IPsec (for a VPN) to start on Linux because it doesn't recognize the interface, which should be PPP I believe, I have PPPd installed and my question is...

Does a ppp connection such as ppp0 or ppp1 start only if you have a modem line or ethernet connection?

Or, how do you start a ppp connection on Linux so a ppp# interface is active?

Thanks.:mrgreen:
