Dungeon Siege 2 IP connection question.

[Talon345]

In pervious games i've been able to use the tc/ip values i've assigned to the computers to work. Think of it as an internet that is only in the house. I have afew mock up websites and so on. They have standard router ips that scale, like 10.31.110.X(1-9). The problem is more that whenever i try it asks to validate and since its not the real net there isn't a way to do that.

EDIT-

My mistake you may not know what i'm talking about, when you go into tc/ip it attempts to validate cdkey and pings a server or somthing. On my normal computer this isn't a problem but well yeah i'm picky i want it to work on my lan boxes.
