基于ASA防火墙的SSL ×××配置
实验拓扑图
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:
