    Connecting to a Cisco Firewall???

      I have recently purchase a Cisco ASA5505 firewall and I want to put my SlingBox HD Pro in a DMZ.
      Here is the current setup:
      1.  Inside zone - where my laptop with SlingMedia client is installed and will be viewing the video feed from SlingBox.  The inside zone will have access to DMZ and Outside zone (Internet) but each zone separated by the ASA5505 firewall.
      2.  DMZ Zone - This is where I plan to put my Slingbox! This zone will have Outside zone (Internet) access.  Only inside zone devices can communicate to Slingbox and not the other way around.
      3.  Outside Zone - This zone is connected to my ISP, hence, internet.  I will have to setup some kind of NAT and ACL to allow slingbox to communicate into the DMZ zone, as natively, Outside zone can't communicate to DMZ zone.
      I have having great deal of problem getting this setup to work.  SlingMedia client seems to insist that the Slingbox be in the same network and find it automatically.  Is it possible to tell the SlingMedia Client where the SlingBox is located (IP)? Since I am putting the SlingBox in DMZ and laptop with SlingMedia Client in Inside zone, it will not find it automatically.
      HELP!!  I love my slingbox and infact, I am using it right now to watch NHL Playoff in my local university campus! How cool is that!
