 * `tunnelTimeout` specifies how long a tunnel connection, including websockets, remains open while the tunnel is idle. The default timeout is `1h`.
 
-* `maxConnections` specifies the maximum number of simultaneous connections that can be established per HAProxy process. Increasing this value allows each ingress controller pod handle more connections at the cost of additional system resources. Permitted values are `0`, `-1`, any value within the range `2000` and `2000000`, or the field can be left empty.

-** If the field has the value of `-1`, then HAProxy will dynamically compute a maximum value based on the available `ulimits` in the running container. This process results in a large computed value that will incur significant memory usage compared to the current default value of `20000`.
