Miao Changyun · Computer Knowledge and Technology · 2009
Tunneling is the key technology for constructing Virtual Private Network(VPN).As the noticeable tunnel protocols,Layer Two Tunneling Protocol(L2TP) and IP Security Protocol(IPSec) are firstly introduced in this paper.we analyze the latent security trouble of Access VPN based on L2TP,and the cause,which restricts the secure creation of IP-VPN with IPSec.Finally we provide the Access VPN solution based on L2TP and IPSEC.
