I have an Aircove VPN router that I must use for my job. For months I have had it connected via ethernet cable to Ethernet 1 port on my Verizon router and it worked fine. Several months ago it stopped working. The Aircove VPN Router has no internet connectivity. I have reset both the Verizon Gateway and the Aircove router many times, have tried different cables, have tried connecting the VPN Router to Ethernet 2 port. Nothing works, the VPN router has an IP address but no internet connectivity. I have connected a Roku by ethernet cable to both Ethernet 1 and 2 ports and it has internet connectivity, so the ports are working but it is like some setting has changed that is blocking my Aircove router from getting any internet connectivity. How do I fix this?
