Thanks for the reply. I already study 1k’s possibilities, tried averything or it must be something very simple or I don’t know what I’m doing. The IP both sides are fixes, my side has a router but the ws 100 is sitting on DMZ, the other side doesn’t have a router, just a computer to feed the WS100. I thougt something with firmware or a need for a gatekeeper. If you have any guess, let me know… at this point I just don’t know what to do…Thanks in advance…Luis.
