You need an IP exemption.

There are instructions in the sticky. I've heard of exemptions taking as long as several months in the past, but I think they tend to be quicker now. I did mine in April of this year and it took 24 hours. It varies.
Just make sure if you are both logged on, you are both playing. They do allow IP exemptions for two players in the same household but they do not allow boxing.
