CAN NOT USE MJ

> [...] I have a rental HUGHES HT2000W Modem and my own NETGEAR R6220

   What, exactly, is connected to what, exactly, how, exactly?  (Hint:
If a device has multiple Ethernet ports, then "connected to device" is
not enough detail.)

   A "HUGHES HT2000W Modem" seems actually to be a modem+router, so you
have cascaded two routers.  Cascading multiple routers can cause
multiple problems, possibly including this one.

   Why are you using the R6220?  If it's to expand your wireless-network
coverage, then you may want to configure it as a wireless access point,
instead of as a full-function router.  

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual.  Look for "Use the Router as a
Wireless Access Point".  

> [...] called Hughes support and they seemed clueless about the ports

   The MagicJack gizmo decides which ports it uses; there's no reason
for Hughes to know anything about them.  And the HT2000W probably does
nothing special with those ports.  I'd guess that no one needs to
"release" any ports (whatever that means), but getting everything
tunneled through two routers may be difficult.  Eliminating one of the
routers (by configuring the R6220 as a WAP) might help.

   An alternative way to eliminate one router would be to configure the
HT2000W as a modem only (making the R6220 your only router), but, in my
quick look at the HT2000W documentation which my Web search found, I
didn't see a way to do that.  And, if you have any devices other than
the R6220 connected to the HT2000W (wired or wireless), then you'd
really want to keep the HT2000W as a modem+router.
