[SOLVED] Whoever joins have STEAM_1:0:0?

[1406595]

So I added myself as this ID: STEAM_1:0:0
And when someone joins, they have that STEAM_1:0:0 too
So whoever joins have admin.
Im using XP
Mani Admin Pluhin 1.2
SRCDS

When I type status, it shows up that my ID is STEAM_1:0:0
Anybody else is STEAM_1:0:0
How do I make the server so my IP is correct.
Im using a router.
