You could check iptables on the remote host. For example, execute the following command on '192.168.12.1':

iptables -L -v

Just because they should be the same doesn't mean they are the same, this should be the first thing you check. If you're using an extension to SNMP to check disks then ensure that it's working correctly on the server and that it's being exposed properly in the SNMPD config.

I've no idea what else might need restarted, you don't provide any information on how the statistics are compiled on the server. Probably nothing.

Look at the check command / script / plugin in your nagios instance and run it manually against that host. Sometimes running the plugin manually may give you more information about why its not getting information from the host.
