No it is the dlinks that need the feature. From what you said I figured you were going to cable one of the dlinks to the verizon so that is supported since it is just a ethernet cable. It is the ability to run in bridge/client mode on the far one that is in question.
You would really only need one dlink running in bridge/client mode and have it directly talk to your fios. I figure you might not be doing that because you dlinks did not support the proper encryption or you had forced the fios to run N only for a performance gain.
