How to Force Host??

How would i force host? would i need some net tools or would i change something in the game?? i just don't know where to start. i searched google but nothing that i trust came up. just some malware programs with ivy backdoor. I trust this community. please help and thanks in advance

I'd like to try to make one, but I'd need to be online and I don't want to take the risk of getting banned.
If you have any account I may try though, lol.

Force Host is only possible in Zombies, in MP it´s deticated servers.

You could try to start a private match as a public one.. but not sure since i never tried it on bo3
