The L2TP—IPSec Support for NAT and PAT Windows Clients feature allows more than one Windows
client to connect to a Layer 2 Tunneling Protocol (L2TP) Network Server (LNS) at one time with IP
Security (IPSec) enabled and a network address translation (NAT) or port address translation (PAT)
server between the Windows client and LNS.
client to connect to a Layer 2 Tunneling Protocol (L2TP) Network Server (LNS) at one time with IP
Security (IPSec) enabled and a network address translation (NAT) or port address translation (PAT)
server between the Windows client and LNS.
Currently, if one Windows client is connected to a Cisco IOS LNS router through a NAT or PAT server
with IPSec enabled, and then another Windows client connects to the same Cisco IOS LNS router, the
first client’s connection is effectively terminated. Enabling L2TP—IPSec Support for NAT and PAT
Windows Clients ensures that Windows client connections in this environment are established and
maintained until the connection is closed.
