Need your help to fix a "no route configured" issue

Hello everybody,
Thank you in advance for your time!

My setup:
World <---> E-interface: 10.0.2.6 <---> snmpfwd-server (agent) < trunking to > snmpfwd-client (manager) <--- E-interface 192.168.1.100 ---> Private device IP 192.168.1.200 (SNMP agent enabled)

Would like to do:
Filter and isolate a private device IP 192.168.1.200

To test: snmpget -d -v1 -c public 10.0.2.6:1161 sysLocation.0

snmpfwd-server and snmpfwd-client are invoked as followed:

snmpfwd-client.py --config-file=client.conf --debug-snmp=all --logging-method=file:client.log --log-level=debug --process-user=user1 --process-group=user1 --daemonize
snmpfwd-server.py --config-file=server.conf --debug-snmp=all --logging-method=file:server.log --log-level=debug --process-user=user1 --process-group=user1 --daemonize

Problem:
Timeout: No Response from 10.0.2.6:1161
