Virtual dial-up protocol for network communication

摘要: A layer two forwarding protocol (L2F) provides virtual direct dial-up service into private networks through public internet providers. An authorized remote client appears as a to the home gateway, even is accessing gateway remotely ISP. The new allows conduct point-to-point link protocols, such (PPP) and serial line interface (SLIP) directly with local network gateway. access server changes from routing mode where communication conducted switching POP simply sends data one port tunnel. tunnel then transmits another port, regardless of header information on transmitted packets. can be managed databases controlled by gain resources not typically accessible internet. conducts an independent authorization session prevent unauthorized transport over independently protocols.
