On the Hellfire side of the Dark Portal, on the alliance half of the platform, you'll see a portal between two mages. That portal takes you to the top of the Mage tower in Stormwind.
There's also another one in Shattrath (the main city in Outland, it's a sanctuary so both factions are welcome there).
