I try to install nextcloud to share my folders with my external work team and in the tutorials it appears that I must have internet access but I open the ports of my TpLink archer AC1750 c7 v2 router and it does not allow me to connect to my omv through the internet.
somebody help me please
I have an arris modem connected to my TpLink c7 router and I open the forwarding port but I don't know if I should open them on the modem too
