French:

Bien sur c'est possible mais votre serveur doit connaître aussi la 
définition du réseau configuré sur votre interface ethernet. Alors ajoutez 
à votre fichier dhcpd.conf une déclaration

subnet 202.87.129.64 netmask 255.255.255.224 { ...}.


Sachez que le routeur entre ces deux réseaux doit transmettre les requêtes 
DHCPDISCOVER du réseau 202.87.145.0/27 vers le réseau 202.87.129.64/27, 
autrement cela ne marchera pas.

Mais bien sur.

English:

Sure it's possible but your server needs to know the subnet configured on 
your ethernet interface. Just add the appropriate subnet declaration of 
your ethernet interface:

subnet 202.87.129.64 netmask 255.255.255.224 { ...}.

You have to know though that the router between your two networks must 
forward DHCPDISCOVER broadcasts from your 202.87.145.0/27-Network to your 
202.87.129.64/27-net (where your DHCP server is) otherwise it won't work. 
On Cisco IOS the statement is "ip helper-address".

Yes that's perfectly possible. We are using here approx. 90 subnets 
distributed on 5 ISC DHCP_Servers for redundant service.
Neither of these is directly connected to the networks where the DHCP 
servers are.
