Hello nginx fans,

I'm using nginx (with ngx_redis2 module) as a redis client, and would
like to establish more than 64511 keep alive connections with a redis
instance. The local port range of Linux is limited to 64511, so I'd like
to set up multiple ip addresses for nginx machine, but I don't know how
to tell nginx to bind local port on multiple ip addresses. Anyone has
the experience? Thanks in advance.
