SNMP OID - Firewall NAT Connection

Hello, I need to perform SNMP monitoring the number of connections that are made when NAT is performed in the firewall. I am looking for the OID of the MIB.
TKS.

If you can not find OID for it, but you can get it from command line on the device, you can always send it ut as Syslog and monitor it.
Look at how I get traffic/resources/dhcp ++ information in my Splunk prosjekt.
See link in my signature.
