Forums Connection Issues HOW???

I WANT TO CONECT 30 PC ON ONE IP ADRESS

i dont know why you are creating another post asking the same question. That isnt something we can help you with, regardless of your reasons. Most networks would kick you off for cloning long before 30 diff pcs with the same ip. If you have a legitimate reason for the need (like running an internet cafe), contact the admins of the network involved. How to contact them should be on their website or you can ask in any help channels listed in the MOTD that you see when you connect to the network.

As you were told in your other post, using all UPPER CASE letters is considered shouting and rude

What you want is known as a 'trigger' which is a function that allows more than the normal amount of clones a network allows, usually only three to allow small home networks, ghosting, etc. Apart from that Parabrat is on the money. You won't get a trigger without a VERY good reason.
