思科pix路由设置DMZ区（邮件服务器）

网络已经配置好，pc机已经可以正常上网，公司需要加一台mail服务器。

PIX配置如下：

 

nameif e2 dmz security 50

ip address dmz 172.100.80.1 255.255.255.0

nat (dmz) 1 0.0.0.0 0.0.0.0 0 0

global (outside) 1 外网iP 

static (dmz,outside) 外网iP 172.100.80.2 net 255.255.255.255 0 0 --//172.100.80.2为mail IP

access-list acl_dmz permit icmp any any

access-group acl_dmz in interface dmz

access-list 100 permit tcp any host 外网ip eq www

access-group 100 in interface outside

 

允许内网ip从dmz口进入

 

access-list no-nat permit ip 172.100.0.0 255.255.255.0 172.100.80.0 255.255.255.0

nat (inside) 0 access-list no-nat

 

允许mail对外收发邮件

access-list acl_dmz permit tcp host 172.100.80.2 any eq 80

access-list acl_dmz permit tcp host 172.100.80.2 any eq 53

access-list acl_dmz permit udp host 172.100.80.2 any eq 53
