Re: Getting Client IP to backend instance application

[Aaron West]

Hi Viranga,

Can I check if you've configured your backend web servers to use either the
X-Forwarded-For or X-Client-IP header in your logging?

Normally you would need to do something like the following:

http://www.loadbalancer.org/blog/iis-and-x-forwarded-for-header
http://www.loadbalancer.org/blog/apache-and-x-forwarded-for-headers

Otherwise without understanding your traffic flow it would appear correct,
it's worth bearing in mind that XFF headers will usually contain the client
IP followed by each successive proxy the connection went through so check
it if contains multiple addresses.

Getting Client IP to backend instance application

[Jayalath, Viranga]

Hi Haproxy team ,

I have a question. I have a backed instance which attached to haproxy
instance. I have requirement to get client  IP in my nodejs application
logs . But how ever im getting the haproxy IP. I refer all your x forwarder
options can use to get client ip but still im getting the haproxy server ip
in my logs. Can you advice any thing i can do .  Below you i will mentioned
configuration changes i used.

# add X-FORWARDED-FOR
option forwardfor
# add X-CLIENT-IP
http-request add-header X-CLIENT-IP %[src]
