Setting up bridge.

["Park, Young K" <ypark_(_at_)_ola_(_dot_)_state_(_dot_)_md_(_dot_)_us>]

Hi, everyone!
 
I have a question about setting up the bridge on v3.1.
 
As I read many articles about the configuration, I found that some of
article mentioning "net.inet.ip.forwarding=1" in /etc/sysctl.conf
 
But, when I checked on www.openbsd.org <http://www.openbsd.org>  manual
page, there is no such option in the bridge page.
 
To setting up the bridge, should I enable the option? or just leave it as
"#net.inet.ip.forwarding=1"?
 
I previously commented out the option. And it worked....(some people may
remember that I am having hard time now =P)
 
Also, what exactly "net.inet.ip.forwarding" does? for what application?
 
Thank you,
 
Young.
