About Double NAT
When a router (Orbi) is connected directly to another router (ISP device), the Doublt NAT condition interferes with a number of applications, such as Port Forwarding, VPN, some types of streaming ser...
Also gaming configurations can be effected by double NAT conditions which is not preferred.
- A 4th suggestion would be to use the 1st routers DMZ or IP-pass through feature for the 2nd router as well to help with double NAT problems seen in these certain senarios. This is the most easiest method IMO.
So I have a situation somewhat related and need help. I have a Netgear MR5100 5G modem running on the ATT network and connected to that is my Orbi router (850) plus 2 satellites. I set up the modem with IP passthrough ON, DHCP OFF, ethernet standby disabled, and usb-c as charge only. I am running into NAT 3 limitations on my PS5 and am wondering if setting up the OpenVPN within the orbi will allow me to fix my NAT problem. I've never dealt with NAT issues before, so forgive my noob status.
OpenVPN is not likely to have any effect on the PlayStation 5 situation.
According to this article, the solution is to use Port Forwarding rules on the Orbi router:
Yeah, I tried that. Also tried DMZ. Also tried changing NAT from "secured" to "open" in the Orbi advanced settings. No change, still strict NAT. I think the problem is the ATT modem. Frustrating. I will scour that article and see if there is something I didn't do correctly.
One quick test is to verify that the Orbi has a 'public' IP address. On the Advanced Tab Home Screen, the box Internet Port should show a public IP address, rather than a private IP address.
