What is acosNatPortLow?

This OID defines the lowest port number in the dynamic port range that the NAT device uses when assigning outbound connection ports. Admins configure this range to avoid collisions with well-known services and to comply with security policies that restrict which ports clients can use. Setting this to 49152 means NAT will only assign ports in the range 49152-65535 for outbound connections, reserving lower ports for servers.
