DVG-2102S x 2 through PPPoE Fibre
We have 2 Digital Voice Global Modems (2 VOIP lines) and would like to use them in our network. One of them is able to connect through some port configurations on the Starhub router (PPPoE). As soon as the second one joins the network, the first VOIP Modem is disrupted and both end up not working.
Anyone knows how this is supposed to work?
