You can configure the router so that it only responds to SNMP requests
from certain hosts:

snmp-server community not_public RO 2

That configures a router to have a community string of not_public, and
also to look at access list 2 when it tries to decide whether or not to
respond to SNMP requests.

That's assuming the router or the firewall aren't blocking SNMP traffic
altogether, and that SNMP is configured to run on the router at all.
It's often good to check these things as occasionally you find a
surprise. :)
