Re: Reverse Proxy with 500k connections

Thanks for the advice.
I implemented this approach. Unfortunately not with 100% success.

When enabling sysctl option "net.ipv4.ip_nonlocal_bind = 1" it is possible to use local IP addresses (192.168.1.130-139) as proxy_bind address.
But than using such an address (other than 0.0.0.0), nginx will produce an error message.
Interesting aspect is: attribute "server" in the log entry is empty.
When using 0.0.0.0 as proxy_bind, everything is fine.

Do you have any ideas?
