Pb routeur 2800 cisco avec snmp

bonjour,
nous possedons un reseau de mngt d'equipements en 83.82.64.xx 255.255.255.224 decoupé en 6 sous reseaux
mon reseau admin est en 83.82.65.0 255.255.255.240 il est composé de 3 serveurs (83.82.65.3 83.82.65.4 83.82.65.5)et de pc d'administration 83.82.65.6 etc ..
nous avons ajouté 2 nouveaux equipements avec une @ip equipement et une @ip ethernet
cette derniere est dans un sous reseau en 83.82.64.xx

test:
quand je suis dans le reseau 83.82.64.xx j'arrive à me connecter sur mon equipement
quand je suis dans le reseau 83.82.65.xx impossible
j'ai donc ajouter 2 routes sur l'interface du routeur ping ok mais impossible de se connecter sur l'equipement
pour superviser je dois utiliser un logiciel pilot de chez sagem que j'ai installé sur mon pc supervision
il utilise le protocole SNMP

pouvez vous m'aidez?
merci d'avance

-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to
use.
