For one of my clients I require the ability to choose the outgoing  
interface  
for proxy\_pass, is it possible?

Also how does nginx currently choose which interface to use on a system  
with  
mutliple?

You can use “proxy\_bind” directive for that (nginx-0.8.22+).

I got a feature request, variable support for proxy\_bind.

[emerg] invalid address “$server\_addr” ☹

Wiki isn’t official, it’s community-contributed documentation.  
There is no official documentation in English.

Feel free to add “proxy\_bind” to the wiki.

Thanks, hoping it will get pushed to trunk. Come on Igor, its a must for  
people running nginx as a foward proxy over multiple IPs
