How to setup floating license for a client PC?

I have a floating license for Altera software including Quartus II, Modelsim SE, Nios II. I setup a license server successfully according to instruction from http://www.altera.com/literature/manual/quartus_install.pdf?gsa_pos=1&wt.oss_r=1&wt.oss=installation%20and%20licensing.

As the license type supports up to three PCs, I want to license two other PCs as well. However, I am not sure how to configure license for all three PCs. Whether I have to 'rehost' in Sefl-service Licensing Center three times or I can setup one server and two other will share license file from this server. I could not find from related materials and the licensing center. So I am trying to post here with a hope that someone who has similar experience or knows related material can help to give me a solution or a clue.

Thanks in advance.
