Can you use Microsofts default vpn software to access a cisco box. I've configured it using Easy VPN server but no such luck. I have a 2801 router IOS (12.4(3i))
The L2TPIPSec 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.
