Cisco ASA5505 Remote VPN Configuration

ivven

最近调试一台5505，感觉很不顺当，按照官方的快速配置文档一路走下来照样不能正常运转。。

为了记录也为了使大家少走弯路，把配置文件留下来提供参考。

修正部分(最终修改版,同4Sep07-end):
1.添加 NO_NAT ACL ,即access-list inside_outbound_nat0_acl extended permit ip 192.168.1.0 255.255.255.0 192.168.10.0 255.255.255.0(内网用户访问VPNPOOL)

应用到nat (inside) 0 access-list inside_outbound_nat0_acl

解决VPN USER不能访问内网的问题


2. 添加access-list splitTunnelAcl extended permit ip 192.168.1.0 255.255.255.0 192.168.10.0 255.255.255.0 (内网用户访问VPNPOOL)
vpngroup username split-tunnel splitTunnelAcl

解决VPN USER不能访问互联网的问题


增加用户配置:
vpngroup username address-pool remote
vpngroup username dns-server 202.102.227.68 202.102.224.68
vpngroup username split-tunnel splitTunnelAcl
vpngroup username password 1234

注释部分:
VPN 用户认证:
1.local user database 认证   ,添加username XXX password xxx
2.group 认证,即 vpngroup XXX等命令,如下


vpngroup username split-tunnel splitTunnelAcl   =(以下是ASA中转换的命令)
group-policy test attributes
dns-server value 202.102.224.68 202.102.227.68
split-tunnel-policy tunnelspecified
split-tunnel-network-list value splitTunnelAcl

                                                                                    

Split tunneling：The ability to simultaneously direct packets over the Internet in
clear text and encrypted through an IPSec tunnel. The VPN device
supplies a list of networks to the VPN Client for tunneled traffic.
You enable split tunneling and configure the network list on the
VPN device.

可以用控制列表于Split tunneling绑定将内网路由发布到客户机，使内网流量从VPN走，别的流量从原有网络走，可达到同时上互联网的作用。
如：
access-list 101 permit ip 192.168.1.0 255.255.255.0 192.168.10.0 255.255.255.0
vpngroup vpn1 split-tunnel 101
