How can I set Forum as Homepage in Vbulletin 4

[Savera]

I have vbulletin installed at a site. It has CMS also enabled. But I want user to see FORUM by default when they open website.

currently it is :
main site url -> CMS 
But I want it to
Main site url --> Forum

I am not able to find any option in vbulletin control panel for changing it. So am I required to make any changes in coding manually ?

I have vbseo installed also so will it effect it ?
I am running Vbulletin 4.1

Thank you!
