ASA防火墙上配置IPSEC_×××和SSL_×××-创新互联
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:

ASA2(config-if)#no sh
ASA2(config-if)#int e0/1
ASA2(config-if)#nameif inside
INFO: Securitylevel for "inside" set to 100 by default.
ASA2(config-if)#ip add 192.168.1.254 255.255.255.0
ASA2(config-if)#no sh
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

私网上公网没问题,但两个私网无法互通
2:配置Site-to-Site ×××
