Remove index.php from URL only on root with Nginx rewrite - wordpress

Question

I'm using Wordpress as root of my website and Invision Power Boards as forum.
http://localhost -> Wordpress
http://localhost/forum -> IPB
I have removed "index.php" from Wordpress URLs successfully with Nginx-rewrite however when I try to use SEO Friendly URLs on IPB, nginx simply returns to Wordpress' 404 page.
My configuration is like this:
#This removes "index.php" from Wordpress URLs
location / {
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?q=$uri&$args;
}
Then I follow this link to modify my nginx conf file in order to be able to use SEO friendly URLs of IPB: http://www.devcu.com/forums/topic/262-furl-friendly-urls-with-ipb-and-nginx/
#This part is to be able to use IPB SEO
location /forum/ {
index index.php;
try_files $uri $uri/ /forum/index.php?$uri&$args;
rewrite ^ /index.php? last;
}
When I click a link on my forum (for example: http://localhost/forum/index.php/forum/51-sport/) nginx simply redirects me to (http://localhost/forum/forum/51-sport/) which displays Wordpress 404 error page.
I have very little knowledge about regex so any help would be appreciated.
This is my whole conf file after modifications, little messy I accept that.

# include /etc/nginx/fastcgi_params;
#REMOVE THIS
#fastcgi_read_timeout 60000;
#fastcgi_send_timeout 6000;
#}
}
Since the last post, I have played with IPB's SEO configurations and I managed to remove "index.php" from URLs. It doesn't effect the result of course. But it seems that location / decides what to do and therefore link is being considered as a Wordpress permalink.
EDIT - Solution
# Upstream to abstract backend connection(s) for php
upstream php {
# server unix:/tmp/php-cgi.socket;
server 127.0.0.1:9001;
}
server {
## Your website name goes here.
server_name localhost;
## Your only path reference.
root /home/username/public_html;
## This should be in your http block and if it is, it's not needed here.
index index.php;
location = /favicon.ico {
log_not_found off;
access_log off;
}
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
location / {
# This is cool because no php is touched for static content
try_files $uri $uri/ /index.php;
}
location /forum {
try_files $uri $uri/ /forum/index.php;
rewrite ^ /forum/index.php? break;
}
location ~ ^/forum/index.php {
if ($args != "") {
rewrite ^ http://www.google.com/ permanent;
}
try_files $uri $uri/ /forum/index.php;
rewrite ^ /forum/index.php? last;
}
location /forum/admin/ {
try_files $uri $uri/ /forum/admin/index.php;
rewrite ^ /forum/admin/index.php? last;
}
location ~ \.php$ {
#NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
include /etc/nginx/fastcgi_params;
fastcgi_intercept_errors on;
fastcgi_pass php;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}
}
