This reminds me, in Star Trek you generally can't teleport through shields (they bend these rules as the plot requires though), is this generally the same across the board in other universes with both shields and teleporters?

I... Don't know. You don't really see this in Halo as teleport tech like that is generally only done by the Forerunners.

however there's a difference between Transporters and Forerunner teleportation tech. Transporters stay within the realm of the universe, Forerunner teleportation uses incredibly precise miniature Slipspace portals (Halo's FTL tech, for those unaware), which circumvent natural protections, but the Covies don't have access to such small scale teleportation. I'd probably say Covie ships would block Transporter attempts, but anything that does extradimensional bullshittery would work.
