(一)定义内外网端口 如果想ping则在内网口配置service-manage ping permit
(二)trust加内网接口 untrust加外网端口
(三)上指下指静态路由 >>>>>>只由(一)和(三)就能ping通防火墙的内&外网接口
(五)定义公网地址组
nat address-group 组名
mode pat
route enable
section 0 公网IP
(四)定义域间安全策略
security-policy
rule name ...
source-zone ...
destination-zone ...
source-address 内网IP段
action permit
(六)定义nat策略
nat-policy
rule name ...
source-zone ...
destination-zone ...
source-address 内网段 (可以不配, 认为是全部内网IP, 如果配置了内网段, 则只内网段可NAT)
action source-nat address-group 公网地址组(上面定义的)
