[Xymon] Use X-Forwarded-For header for client IP?

[Shawn Heisey]

I have all my websites behind a reverse proxy.  For those who might be 
interested, it's haproxy.  I'm using it because it handles all the TLS 
and can be easily configured to handle DDOS attacks.

Is it difficult to get xymon to use the X-Forwarded-For header?  Did 
some googline and came up empty.  I have some disabled tests, and this 
is what it says:

Disabled by: elyograg @ 127.0.0.1

I would like to see the real IP address there.  I've got Xymon 4.3.28 
installed from source.

Thanks,
Shawn
