ASA防火墙上配置IPSEC_×××和SSL_×××

ASA防火墙上配置IPSEC ×××和SSL ×××

一:实验拓扑:

二:实验要求:

1:PC1属于上海分公司内网主机,PC2属于总公司主机.要求上海分公司的用户直接可以喝总公司的PC2通信.(Site-to-Site IPSEC ×××实现)

2:公网上用户可以访问总公司的OA服务器PC2.(SSL ×××实现)

三:配置过程:

1:基本配置:

ASA1(config)#int e0/1

ASA1(config-if)#nameif inside

INFO: Securitylevel for "inside" set to 100 by default.

ASA1(config-if)#ip add 172.16.1.254 255.255.255.0

ASA1(config-if)#no sh

ASA1(config-if)#int e0/0

ASA1(config-if)#nameif outside

INFO: Securitylevel for "outside" set to 0 by default.

ASA1(config-if)#ip add 12.0.0.1 255.255.255.0

ASA1(config-if)#no sh

ASA1(config-if)#

ASA1# ping172.16.1.1

Type escapesequence to abort.

Sending 5,100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:

配置路由,NAT,ACL

ASA1(config)#route outside 0 0 12.0.0.2

ASA1(config)#nat-control

ASA1(config)#nat (inside) 1 0 0

ASA1(config)#global (outside) 1 interface
