SNAT/X-Forwarded

Hi Donster,

just the 1st pair has to insert the

X-Forwarded-For

header. This can be done by using a Standard VS with HTTP Profile attached and either

X-Forwarded-For

HTTP Profile settings enabled or by disabling the

X-Forwarded-For

HTTP Profile settings and deploying an iRule like this...

when HTTP_REQUEST {
    HTTP::header remove "X-Forwarded-For" 
    HTTP::header insert "X-Forwarded-For" [getfield [IP::client_addr] "%" 1]
}

Note: You could also use the iRule of my previous post, if you need to consolidate existing

X-Forwarded-For

headers into a unified header.

On the second unit you may also use a Standard VS with HTTP Profile attached - but you don't have to. If a HTTP Profile is getting attached, then you have to make sure that the

X-Forwarded-For

HTTP Profile settings are disabled.

Cheers, Kai
