Hi there! Moderate NAT normally indicates that your connection has some restrictions on it. These restrictions could prevent you from participating in certain activities and receive error codes or other network-based error codes. This could be coming from either a hardware firewall, a misconfigured router setting, or a software firewall. We would not be able to provide any guidance on any particulars, as these are all variables that are based on your home configuration. Please review the Advanced Troubleshooting Guide for more information on what the NAT status means and what you can do to mitigate it. https://help.bungie.net/hc/en-us/articles/360049496751-Advanced-Troubleshooting-UPnP-Port-Forwarding-and-NAT-Types
