Xforwarded Property

Hi Huseyin,

You can log the X-Forwarded-For value using an iRule to make sure it's being inserted:

when HTTP_REQUEST priority 501 {
   log local0. "XFF's: [HTTP::header values X-Forwarded-For]"
}

I wonder if Avaya can't handle multiple XFF header values. If that's the case, you could have LTM remove any existing XFF headers using a custom HTTP profile with the header to remove set to X-Forwarded-For and the header to insert set to X-Forwarded-For: [IP::client_addr].

If that's not it and you see the XFF being inserted from LTM, I'd try contacting Avaya again.
