Hi, I'm new in a forum, but I have a big problem and I don't find the solution, maybe you can help me.

I have an application on VB 6.0, It has 2 parts, one client, and one server.
The client, conect to the server with
CreateObject("appserver.object",myserver). THAT'S WORK.

But, now the user of this app, put a firewall on his network, and my app doesn't work.
They ask me, what ports they have to open to my app work, but I don't know.

Can anybody help me?

Thanks, and excuse my english.
