both things can be used together like phpnuke on phpbb2 forum main page?

Your Nuke interface or main section is a portal. phpBB2 is a ported module that is for the forums. Nuke 6.0 comes loaded with what is called splatt forums. If you upload phpNuke 6.5 it comes loaded with the phpBB2.0.6 ported mods forums.

Use it for a new install and you will be good. Here is a link to 6.5 download and unzip, upload to server and follow the instructions int he INSTALL.txt file. After that if you have trouble we are here for ya. You will need to register first.

For the record Nuke 6.5 - 6.8 come with a ported version of phpBB 2.0.4
