随着网络技术的飞速发展，远程办公和远程访问的需求不断攀升，VPN（虚拟专用网络）作为一种安全且高效的远程访问解决方案，被广泛应用于各个领域，本文将深入解析思科VPN的配置步骤，旨在帮助您轻松搭建安全的远程连接环境。
思科VPN配置步骤详解
1. VPN服务器配置
（1）创建VPN策略
在思科设备的命令行界面中，执行以下步骤：
Router# ip local pool VPNPOOL 192.168.1.100 192.168.1.199 Router# ip access-list standard VPNACCESS Router# permit 192.168.1.0 0.0.0.255 Router# ip route 0.0.0.0 0.0.0.0 192.168.1.1 Router# crypto isakmp policy 1 Router# isakmp key mykey address 192.168.1.1 Router# crypto map VPNMAP 1 ipsec-isakmp Router# set crypto map VPNMAP 1 match address VPNACCESS Router# set crypto map VPNMAP 1 set peer 192.168.1.1 Router# set crypto map VPNMAP 1 encryption 3des Router# set crypto map VPNMAP 1 authentication pre-share Router# set crypto map VPNMAP 1 authentication group 2 Router# set crypto map VPNMAP 1 auto-negotiate Router# interface tunnel 0 Router# tunnel source GigabitEthernet0/0 Router# tunnel destination 192.168.1.1 Router# tunnel mode ipsec Router# tunnel group VPNPOOL 1 Router# tunnel key mykey Router# no shutdown
（2）配置IPsec协议
Router# crypto isakmp key mykey address 192.168.1.1 Router# crypto ipsec transform-set VPNTRANS esp-3des esp-sha-hmac Router# crypto ipsec security-association lifetime seconds 28800 Router# crypto ipsec security-association lifetime kilobytes 460800 Router# crypto ipsec profile VPNPROFILE Router# set crypto ipsec profile VPNPROFILE transform-set VPNTRANS Router# set crypto ipsec profile VPNPROFILE mode tunnel Router# set crypto ipsec profile VPNPROFILE proposed-group 2
2. VPN客户端配置
（1）创建VPN策略
