cisco 2509 router has 8 async ports that can be used to dial in or out. if configured for dial out, each asyn interface would be allotted an IP address when it dials into its ISP and establishes a PPP link. 8 PPP links would mean 8 IP address. why would one have such a configuration and what is its use. As far as dialling-in is concerned, most ISP use like PortMaster (Livingstone) and it allotes an IP address to the host dialling into it from its pre-configured IP addresses and a PPP link is established. hence in such a scenario where would one install a 2509 router ? or am i missing something here... thanks john __________________________________________________ Do You Yahoo!?
