“DNS穿透搞不定了，自己搞定了总结

asa防火墙是不允许内网访问外网口地址的，所以我内网访问域名的时候，域名被解析成外网口地址，内网就不能通过域名访问网站了，我在static语句后面加上dns了，也不行，这种情况怎么解决？

配置如下：
interface Vlan1
nameif inside
security-level 100
ip address 192.168.0.1 255.255.255.0
!
interface Vlan2
nameif outside
security-level 0
pppoe client vpdn group bohao
ip address pppoe setroute

switchport access vlan 2
