HAProxy-expert understanding the TCP Transparent mode (TProxy) needed

- I want to use HAProxy in front of my webserver(s) using TCP in transparent mode (TProxy)! (Yes, really!) How do I setup this for CentOS 7? All servers (haproxy and webservers) are in the same subnet. Is that a problem? I am in an evironment using NAT (by the outside router/firewall). Is that a problem?

- The default gw on my webservers will be the HAProxy, right? Anyway, is there a way to route only the webtraffic-answers through HAProxy while SSH and DNS are using the a different gw? This is essentail, because the web-machines contact other hosts to generate the content (e.g. DB) or get diretcly contacted from the monitoring tools.

- How do I block special IP/Nets using HAProxy.

- How do I block client after N concurrent connections?

- How do I see what's currently going on? (e.g. number of current connections, bandwidth of each connection, etc)

- How do I see logs?

- How do I reload the HAProxy config without loosing even one packet?

I don't like this idea: [login to view URL]

Is that possible for our usecase: [login to view URL]

I have this setup:


[login to view URL] public ip

[login to view URL] public ip

[login to view URL] public ip


[login to view URL] public ip

[login to view URL] and :443

[login to view URL] and :443


[login to view URL] public ip

[login to view URL] and :443

[login to view URL] and :443

I am able to SSH to,,

Tcp traffic to port 80 and 443 to and will go to [login to view URL] or

Now your job:

How to lb[login to view URL] to [login to view URL] and [login to view URL] in transparent TCP mode? (Plus the other ports and IPs.)
