how-to alter .htaacess to handle subdomains properly.

Hi,
I am currently running couple of sub-domains via our main domain: http://www.techarena.in

Here are the sub-domains in use:
http://forums.techarena.in
http://gallery.techarena.in

This is the .hta code used currently:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^207\.58\.143\.178$
RewriteRule ^/?(.*)$ http://www.techarena.in/$1 [R=301,L,NS]

ErrorDocument 400 /
ErrorDocument 401 /
ErrorDocument 403 /
ErrorDocument 404 /
ErrorDocument 500 /

Code (markup):

I am re-directing all the traffic from our Domain IP to domain via above code, and also re-directing all the 404 and/or error pages to respective portal.

I want to acheive following things:
I want to re-direct all the traffic coming from www.techarena.in/forums/ to http://forums.techarena.in

and re-direct all the traffic coming from www.techarena.in/gallery/ to http://gallery.techarena.in

I have many threads indexed in this fashion on google and yahoo as well:
http://www.techarena.in/forums/showthread.php?t=346155

The above url should be re-directed appropriately to http://forums.techarena.in/showthread.php?t=346155

Thanks in advance for your help.
