Port Forwarding in Huawei LTE Routers using "DMZ" Settings
- This will forward All Protocols and All Ports to the nominated "DMZ IP".  - Configure the DMZ zone as per this screenshot HuaweiEnableWANPing.png 
- Configure the router to respond to ping on the WAN port as per this screen shot HuaweiDMZConfiguration.png 
 
- The above screenshots were made and tested with a Huawei router with the following details:
| Device name | B315s-936 | 
| Hardware version: | WL1B310TM02 | 
| Software version: | 21.311.03.00.1232 | 
Other devices can be expected to behave differently.
