Hi: I've installed SonicWall VPN Client on a laptop which can then successfully connect to the office's server if I'm connected to the Internet with Comcast Cable. However if I am at another site where the access if DSL DSL (with PPPoE) the connection is refused. The DSL modem is connected directly to the laptop; no router. I read elsewhere that a router is required to negotiate between the sonicWall and PPPoE protocols--? Any other suggestions?
