TL;DR: portforwarding does not work although i have done everything i can imagine to make it work. pls help. Formal version below.
Router = TL-MR3420 V3

Dear Ladies and Gentlemen,
Portforward or DMZ seems not to work on the described router.
Service is not reachable from "outside" (Internet).
If i plug the UMTS/3G Modem (Usb-Stick) straight into my computer, my service is properly reachable from outside as it should be.
If it is connected to the router, it won't be reachable from "outside" (Internet).
Inside the LAN, the service is reachable properly.
What i have tried so far - without success:
- list computer with running service as DMZ-Host
- add "Virtual Server" ("Forwarding" Menu)
- add Port-Triggers ("Forwarding" Menu)
- change Firewall Status of router ("Security" Menu)
- change IP-adress for LAN
- assign static IP to computer with running service
- disable DHCP
- change port for remote management
I furthermore noticed in the DMZ menu there is a note saying
" Note: Make sure the nat is enable if you want the DMZ configuration take effect. "
Where / how can i make sure the NAT is enabled?
I cannot find the option described in this link which shows the green UI: https://www.tp-link.com/us/support/faq/540/
I am looking forward to read from you.
