Podepnę się do tematu - bardzo podobny problem. Mam TP-Link TL-MR3420 oraz podpięty na USB modem 3G. Wgrałem wersję 1.4.1 (r28127), by obsy.
Przekierowanie portów nie działa (chciałem mieć dostęp do serwerka za routerem poprzez VNC i RDP). Nie jest to kwestia operatora, mam wykupioną usługę adresu publicznego. Do samego routera mogę dostać się z zewnątrz, ale już przekierowanie portów nie działa, muszę ratować się ssh - a nie jest to zbyt wygodne rozwiązanie.
