Although, dmz can only be enabled to one device ip (computer, tablet, console, etc..) on the modem/router.Exactly, dmz can provide port forwarding for 1 computer only.
Also why don't you encourage those 2 to come forth on the forum instead of having an intermediary speak for them, they would learn more if they are proactively looking for their own solution.Sure, why not to register on forum and ask that themselves? It will take 1 min and will be much more useful to them.
