Last year I obtained a copy of V2 SSDR and a new win10 I7 laptop to be able to operate my Flex remotely using SmartLink. I was unable to connect the two as was Flex support using TeamViewer. The conclusion was that my ISP, ATT, uses a double NAT to supply my Internet.
I was offered help by an independent individual who indicated he had been able to successfully use the same or similar device with SmartLink. I followed his instructions but the modem bricked just outside of warranty requiring a new purchase.
Has anyone found a workaround for the ATT double NAT problem? If not, are only a few Flex uses affected allowing this limitation to be ignored?
