Nostalrius Begins - Quality wow vanilla realm (1.12)

me playing on my computer and he playing on his computer helping me level is against rule? thanks

No, as long you are both playing your accounts then it is perfectly legal.

To avoid false multiboxing reports, don't use /follow at any time.

andd. what if game master see 2 character logged from 1 ip adress? (us two) and assume it cheating. is there some ways to tell that it is 2 computer even if 1 adress?

thanks

They use more than only same IP as a way to detect multiboxing. That is why I don't recommend doing /follow

My wife and I play all the time from the same IP address, often in the same group. IP address alone is not used to determine multiboxing. As Mlmma says, don't go on follow and it will be clearly obvious whether there are two players playing the two accounts (or not).
