You may have to reconfigure your router since a typical DSL modem also has NAT, which complicates things a lot. A satellite modem on the other hand, typically does not have NAT.
MayBe You Should Try Looking In The Back Of Your Router And If It has A Red Blue Or Black Button On The Back Press It And Hold It Down For 10 To 20 Sec's I Hope I Was Help If That Dont Work Then Somethings Wroug With It!!
