Laowai, I agree that the Order would probably give the Corsairs the codes in exchange for credits/ships...
But it is not valid to be smuggling through it. It is probably the most heavily guarded and one of the most dangerous systems in Sirius, with Nomads, Order, Bounty Hunters and LN ships attacking each other left right and centre.
A smuggling ship, in-RP, would not get out of there alive. Codes or not, he'd be destroyed by the supposed defenses at either side of the gate. However, they are made useless in the mod for the single player campaign.
