i would to Feature Request an Addition of "Full Cone NAT" / "NAT Filtering: Open" Toggle
The Problem is
Currently, the Netduma R3 (DumaOS 4) lacks an explicit "NAT Filtering: Open/Secure" toggle. While the R3 supports PCP and UPnP, these protocols often result in a "Moderate" NAT type on PC for games with Peer-to-Peer (P2P) architectures, most notably Grand Theft Auto V.
Symmetric vs. Full Cone NAT: By default, the R3 appears to use "Restricted" or "Symmetric" NAT filtering. While this is secure, it is incompatible with many P2P matchmaking systems. Even when ports (like UDP 6672) are opened via PCP, the NAT remains "Moderate" because the router only allows incoming traffic from the specific IP/Port that the PC first contacted.
The "Full Cone" Requirement: For an "Open" NAT in GTA V, the router must support Full Cone NAT (Endpoint Independent Mapping). This allows any external host to send packets to the internal PC via the mapped port, regardless of whether the PC has messaged them first.
Regional Necessity (Australia/Oceania): For players in Australia, the player pool is smaller. A "Moderate" NAT limits the number of successful P2P handshakes, leading to much smaller or empty lobbies, "Timed Out" errors, and increased latency. when playing with some other friends i previously had no issues with, since i had a router that allowed me to set Nat filter to open.  An "Open" NAT is not just a label; it is a requirement for stable connectivity in isolated regions.
The Solution here is
I am requesting the addition of a "NAT Filtering" toggle in the WAN settings (similar to those found on Netgear, ASUS, and TP-Link hardware) that allows users to switch from "Secured" to "Open".
because DMZ is not an answer:
Using the DMZ is a "sledgehammer" approach that exposes the entire device to the internet. A "Full Cone NAT" or "Open Filtering" option provides the same connectivity benefits for gaming while maintaining a higher level of security by only affecting how active port mappings are handled.

so for goodness sakes add this feature, it would actually help MANY people out with the multitude of complaints about Nat type open and especially for an issue like one console having open Nat and the other 2 having moderate or strict

Je n'utilise pas du tout le filtrage géographique(i do not use Geo Filtering at all)

i've tried both disabling the advanced part with DPI and the regular toggle for smart boost
