拓朴图

实验目的，PC2通过SSL×××能够访问到PC1

SSL×××服务端配置全在ASA上面，下面为配置步骤：

第一步：建立RSA密钥证书，名称为ssl***keypair

crypto key generate rsa label ssl***keypair

第二步：建立自我信任点CA，名称为localtrust。加载RSA密钥证书

crypto ca trustpoint localtrust
  enrollment self
  fqdn ssl***.luotao.com
  subject-name CN=ssl***.luotao.com
  keypair ssl***keypair
  crypto ca enroll localtrust noconfirm
  exit

第三步：将CA信任点localtrust应用到OUTSIDE口

ssl trust-point localtrust outside

第四步：将客户端上传到ASA并安装，开启SVC在outside口。

copy tftp disk0:
web*** 
 svc p_w_picpath disk0:/sslclient.pkg 1
 svc outside
 svc enable
 exit

第五步：建立clientpool，给客户端分配IP

ip local pool sslclientpool 10.10.10.10-10.10.10.50 mask 255.255.255.0

第六步：创建组策略名为sslclientpolicy，设置类型；组策略属性包括设置DNS，指定隧道协议SVC，设置域名，加载客户端pool

group-policy sslclientpolicy internal
group-policy sslclientpolicy attributes
 dns-server value 202.96.134.133
 ***-tunnel-protocol svc
 default-domain value luotao.com
 address-pools value sslclientpool
 exit

第七步：设计访问列表旁路，×××流量不受outside口ACL限制。

sysopt connection permit-***

第八步：创建tunnel-group隧道组sslclientprofile，组属性包括加载组策略sslclientpolicy，以及设置登陆时看到的组名称ssl***client

tunnel-group sslclientprofile type remote-access
tunnel-group sslclientprofile general-attributes
 default-group-policy sslclientpolicy
tunnel-group sslclientprofile web***-attributes
 group-alias ssl***client enable
 exit

第九步：开启tunnel-group列表功能，开启则在SSL客户端显示GROUP名称，否则不显示。

web***
 tunnel-group-list enable
 exit

第十步：配置NAT免除，不让SSL×××的流量经过NAT

access-list nat0 extended permit ip 192.168.1.0 255.255.255.0 10.10.10.0 255.255.255.0

nat (inside) 0 access-list nat0

第十一步：建立本地用户，供SSLCLIENT登陆时使用。

username cisco password cisco
username cisco attributes
 service-type remote-access
 exit

第十二步：配置隧道分离，用ACL匹配流量，应用到组策略中。作用是在访问SSL×××的同时，还可以访问internet与其它网络。

access-list splitssltunnel standard permit 192.168.1.0 255.255.255.0
group-policy sslclientpolicy attributes
 split-tunnel-policy tunnelspecified
 split-tunnel-network-list value splitssltunnel

exit

第十三步：保存配置

save

在PC2上输入  https://1.1.1.1  按照步骤配置客户端

客户端状态

隧道分离

测试：

ping 192.168.1.2    OK

访问PC1上的FTP      OK

最后上全部配置文件：
