Thanks for answer.
 
So on my case, what should I add to tell the the server to allow the second
IP subnet ?

If your DHCP server is not on the same subnet as the clients you want to
serve, you need a 'helper' to tell the DHCP server that some one from
subnet 202.87.145.0 wants an IP address.
 
In your case, the server is hearing a broadcast directly from a client
and assumes it needs an IP address from the same subnet as the server is
on.  And that is exactly what the message is telling you, I don't have
any availible address on this subnet.
