Here are the details of my configuration file.  What I am not sure of is the

This means, that the connections  cannot be established within  5 seconds
(which is the default).
Actually, it looks like, that you may have no route. One can use any
addresses, providing, that you ensure a smooth
route from client and from server for the addresses you use.

Please, start with a single client and see that it works, than progress
further.

IP_ADDR_MIN and IP_ADDR_MAX.
The addresses from the same network should be routable to
192.168.0.40<http://192.168.0.40/index.html>,
e,g,
192.168.0.41 up to 192.168.1.255.

When you are specifying any addresses here, they are added by curl-loader
initialization to the network
interface eth0 and may be seen by the command:
#ip addr

Command ping (man ping) has an option -I to force the ping to be issued from
a certain ip-address. To test, that your routing is OK, you may use, e.g.
#ping -I <the address you wish to use>
192.168.0.40<http://192.168.0.40/index.html>
When it works - it will be OK.

Y may also wish to read a bit into the linux routing/networking HOWTOS.
