实验anyconnect 4.2；ASA55059.2(4)
ASA版本如下：
System image file is "disk0:/asa924-k8.bin"
实验需求：
1.远程PC使用SSLVPN拨入访问内网server
2.使用用户A和用户B拨入后的IP不在同一网段。
配置步骤如下：
第一步：配置身份证书
在这里我们生成一个名为sslvpnkeypair的自签名证书，并将这个自答名证书应用在“outside”接口上面。默认情况下，我们的安全设备每次重新启动以后，都全重新生成我们的证书，这个证书我们也可以从厂商购买自己的证书，这个证书即使我们的网络设备重启了它仍然存在。//生成一个RSA密钥的证书，该名称是是唯一的。
CISCOASA(config)# crypto key generatersa label sslvpnkeypair
INFO: The namefor the keys will be: sslvpnkeypair
Keypairgeneration process begin. Please wait...
//建立一个自我信任点颁发的证书
CISCOASA(config)#crypto catrustpoint localtrust
CISCOASA(config-ca-trustpoint)# enrollment self
CISCOASA(config-ca-trustpoint)#fqdn sslvpn.luxshare.com
CISCOASA(config-ca-trustpoint)#subject-nameCN=sslvpn.luxshare.com
CISCOASA(config-ca-trustpoint)#keypair sslvpnkeypair
CISCOASA(config-ca-trustpoint)#crypto caenroll localtrust noconfirm
% Thefully-qualified domain name in the certificate will be: sslvpn.cisco.com
CISCOASA(config)#ssltrust-point localtrust outside
第二步：将SSL VPN客户端映象上传到ASA
用户可以从思科的网站(cisco.com)获得客户端映象。在选择要下载哪个映象给TFTP服务器时，记住你需要为用户所使用的每种操作系统下载单独的映象。在选择并下载客户端软件后，就可以将其TFTP到ASA。
CISCOASA(config)# copy tftp://192.168. 1.50/anyconnect-win-4.2.00096-k9.pkg flash:/
我这里用的anconnect是-4.2.00096版本。
在将文件上传到ASA之后,配置一下这个文件,使其可用作Web VPN会话.注意,如果你有多个客户端,就应当配置最常用的客户,使其拥有最高的优先权。在本文中，我们将仅使用一个客户端并为其设置优先权为1：当mac和linux访问时使用2 3
CISCOASA(config)# webvpn
CISCOASA(config-webvpn)#anyconnect imagedisk0:/anyconnect-win-4.2.00096-k9.pkg 1
INFO: Imagedoes not contain head-end configuration.
CISCOASA(config-webvpn)#anyconnect imagedisk0:/anyconnect-macosx-i386-4.2.00096-k9.pkg 2
CISCOASA(config-webvpn)#anyconnect imagedisk0:/anyconnect-linux-64-4.2.00096-k9.pkg 3
第三步：启用SSL VPN访问
如何不启用的话，那么我们输入网址将打不开该SSL VPN的页面。
CISCOASA(config-webvpn)# enable outside
CISCOASA(config-webvpn)#anyconnect enable
CISCOASA(config-webvpn)#exit
第四步：建立SSL VPN拨号地址池
远程访问客户端需要在登录期间分配一个IP地址，所以我们还需要为这些客户端建立一个DHCP地址池，不过如果你有DHCP服务器，还可以使用DHCP服务器。
CISCOASA(config)# ip local pool SSLClientPool 192.168.254.10-192.168.254.100 mask 255.255.255.0
第五步：创建组策略
组策略用于指定应用于所连接客户端的参数。在本文中，我们将创建一个称之为SSLCLientPolicy的组策略。
CISCOASA(config)# group-policy SSLClientPolicy internal //打完此命令才有下面的属性设置命令
CISCOASA(config)#group-policy SSLClientPolicy attributes
CISCOASA(config-group-policy)#dns-servervalue 192.168.1.20 //内网DNSServer IP
CISCOASA(config-group-policy)# vpn-tunnel-protocol ssl-client
CISCOASA(config-group-policy)#group-lock value SSLClientProfile
//组锁定tunel-group SSLClientProfile，创建后才能敲。选配；
CISCOASA(config-group-policy)#default-domainvalue luxshare.com
CISCOASA(config-group-policy)#split-dns value luxshare.com
//启用了spilt-dns后 只有luxshare.com的域名送往内部dns服务器解析。选配；
CISCOASA(config-group-policy)# address-pools valueSSLClientPool
CISCOASA(config-group-policy)# exit
第六步：配置访问列表旁路
通过使用sysoptconnect命令，我们告诉ASA准许SSL/IPsec客户端绕过接口的访问列表
CISCOASA(config)# sysopt connection permit-vpn
第七步：创建连接配置文件和隧道组
在远程访问客户端连接到ASA时，也就连接到了connection profile连接配置文件，也称为隧道组。我们将用这个隧道组来定义其使用的特定连接参数。在本文中，我们将配置这些远程访问客户端使用Cisco SSL VPN客户端，不过，你还可以配置隧道组使用IPsec、L2L等。
首先，创建隧道组SSL 客户端：CISCOASA(config)# tunnel-group SSLClientProfile type remote-access
下一步就是给这个SSLVPN隧道分配特定的属性CISCOASA(config)# tunnel-groupSSLClientProfile general-attributes
CISCOASA(config-tunnel-general)#default-group-policy SSLCLientPolicy
CISCOASA(config-tunnel-general)# tunnel-groupSSLClientProfile webvpn-attributes
CISCOASA(config-tunnel-webvpn)# group-alias SSLVPNClient enable
CISCOASA(config-tunnel-webvpn)# exit
在上在group-alias后面的SSLVPNClient这个就是我们在登陆页面提示进行登录时看见的组。(如下图：)
第八步：将隧道组列表在webvpn中开启
开启之后，在我们登录的时候才会有“GROUP”，如果没有开启的话，在上图就没有“GROUP”这个列表。
CISCOASA(config)# webvpn
CISCOASA(config-webvpn)#tunnel-group-list enable
CISCOASA(config-webvpn)# exit
第九步：配置NAT免除
现在，我们需要告诉ASA不要对远程访问客户端和要访问的内部网络之间的通信进行网络地址转换
(NAT)。首先，我们要创建定义通信的object ，然后，我们将这两个object互访时自己转换成自己：
ciscoasa(config)# object network SSLVPN-Pool
ciscoasa(config-network-object)# subnet 192.168.254.0 255.255.255.0
ciscoasa(config)# object network Internal
ciscoasa(config-network-object)# subnet 192.168.1.0 255.255.255.0
ciscoasa(config)# nat (inside,any) source static Internal Internal destination static SSLVPN-Pool SSLVPN-Pool no-proxy-arp route-lookup
第十步：配置用户账户
现在我们已经为配置用户账户做好了准备。在此，我们要创建一个用户并且将此用户指派给我们的SSLClientPolicy中：
CISCOASA(config)# username tom password 123456
CISCOASA(config)# username tom attributes
CISCOASA(config-username)#service-typeremote-access
CISCOASA(config-username)# vpn-group-policy SSLClientPolicy
CISCOASA(config-username)# exit
第十一步：保存CISCOASA(config)#writememory
隧道分离技术：
从这里我们可以看见，我们所有的数据都走向我们SSL VPN服务端去了。所以我们现在就只能访问SSL VPN服务端的网络了。但是我自己这边的网络以及互联网都不能访问，这样我们就非常不方便。那么我们如何来解决这个问题呢?我们在这里就必须使用隧道分离技术了。那么下面我们来看看隧道分离如何配置呢?
CISCOASA(config)# access-list vpnclient_splitTunnelAcl standard permit192.168.1.0 255.255.255.0
CISCOASA(config)# group-policy SSLClientPolicy attributes
CISCOASA(config-group-policy)#split-tunnel-policytunnelspecified
CISCOASA(config-group-policy)#split-tunnel-network-list value vpnclient_splitTunnelAcl
CISCOASA(config-group-policy)#exit
如法炮制创建组另一个组：
CISCOASA(config)# ip local pool SFCSClientPool 192.168.253.10-192.168.253.100 mask 255.255.255.0
CISCOASA(config)# group-policy SFCSClientPolicy internal //打完此命令才有下面的属性设置命令
CISCOASA(config)#group-policy SFCSClientPolicy attributes
CISCOASA(config-group-policy)#dns-server value 192.168.1.20 //内网DNSServer IP
CISCOASA(config-group-policy)# vpn-tunnel-protocol ssl-client
CISCOASA(config-group-policy)#group-lock value SFCSClientProfile
//组锁定tunel-group SSLClientProfile，创建后才能敲。选配；
CISCOASA(config-group-policy)#default-domain value luxshare.com
CISCOASA(config-group-policy)#split-dns value luxshare.com
//启用了spilt-dns后 只有luxshare.com的域名送往内部dns服务器解析。选配；
CISCOASA(config-group-policy)# address-pools value SFCSClientPool
CISCOASA(config-group-policy)# exit
首先，创建隧道组SSL 客户端：CISCOASA(config)# tunnel-group SFCSClientProfile type remote-access
下一步就是给这个SSLVPN隧道分配特定的属性CISCOASA(config)# tunnel-group SFCSClientProfile general-attributes
CISCOASA(config-tunnel-general)#default-group-policy SFCSClientPolicy
CISCOASA(config-tunnel-general)# tunnel-group SFCSClientProfile webvpn-attributes
CISCOASA(config-tunnel-webvpn)# group-alias SFCSVPNClient enable
CISCOASA(config-tunnel-webvpn)# exit
ciscoasa(config)# object network SFCSVPN-Pool
ciscoasa(config-network-object)# subnet 192.168.253.0 255.255.255.0
ciscoasa(config)# nat (inside,any) source static Internal Internal destination static SFCSVPN-Pool SFCSVPN-Pool no-proxy-arp route-lookup
CISCOASA(config)# username Alice password 123456
CISCOASA(config)# username Alice attributes
CISCOASA(config-username)#service-type remote-access
CISCOASA(config-username)# vpn-group-policy SFCSClientPolicy
CISCOASA(config-username)# exit
CISCOASA(config)# group-policy SFCSClientPolicy attributes
CISCOASA(config-group-policy)#split-tunnel-policy tunnelspecified
CISCOASA(config-group-policy)#split-tunnel-network-list value vpnclient_splitTunnelAcl
CISCOASA(config-group-policy)#exit
ciscoasa(config)# show run
