root@SRX550# set interfaces ge-0/0/0 unit 0 family inet address 110.250.250.2/24
root@SRX550# set interfaces ge-0/0/1 unit 0 family inet address 192.168.1.1/24

3.2 将1口加入trust域

root@SRX550# set security zones security-zone trust interfaces ge-0/0/1.0

3.3 将0口加入untrust域

root@SRX550# set security zones security-zone untrust interfaces ge-0/0/0.0

四、路由配置

4.1 默认路由

root@SRX550# set routing-options static route 0.0.0.0/0 next-hop 110.250.250.1

4.2 静态路由

root@SRX550# set routing-options static route 172.16.0.0/24 next-hop 192.168.1.254

五、策略配置

5.1 创建端口组Service_1433及对应端口：

root@SRX550# set applications application Service_1433 term Service_1433 protocol tcp
root@SRX550# set applications application Service_1433 term Service_1433 source-port 0-65535
root@SRX550# set applications application Service_1433 term Service_1433 destination-port 1433-1433

5.2 创建应用组Service_allow，并将Service_1433加入到应用组：

root@SRX550# set applications application-set Service_allow application Service_1433

5.3 创建地址组

root@SRX550# set security zones security-zone trust address-book address 172.16.0.0/24 172.16.0.0/24
root@SRX550# set security zones security-zone trust address-book address 172.16.0.253/32 172.16.0.253/32

5.4 创建地址池neiwang_allow，并将允许访问外网的地址组加入进来

root@SRX550# set security zones security-zone trust address-book address-set neiwang_allow address 172.16.0.0/24

5.5 创建域间规则策略从trust到untrust

root@SRX550# set security policies from-zone trust to-zone untrust policy 1 match source-address neiwang_allow
root@SRX550# set security policies from-zone trust to-zone untrust policy 1 match destination-address any
root@SRX550# set security policies from-zone trust to-zone untrust policy 1 match application any
root@SRX550# set security policies from-zone trust to-zone untrust policy 1 then permit

5.6 创建域间规则策略从untrust到trust，允许访问内部172.16.0.253的1433端口

root@SRX550# set security policies from-zone untrust to-zone trust policy 1 match source-address any
root@SRX550# set security policies from-zone untrust to-zone trust policy 1 match destination-address 172.16.0.253
root@SRX550# set security policies from-zone untrust to-zone trust policy 1 match application Service_allow
root@SRX550# set security policies from-zone untrust to-zone trust policy 1 then permit
