Hello OpenWRT users, I have two OpenWRT boxes one DSL-502T (ADSL-modem-router) and one RT-N16 (router with substantially more power) I'm trying to avoid a double NAT, and offload as much processing to the RT-N16 (so bridging the WAN and LAN isn't an option) the simple thing would be to set the DSL-502T to PPPoE but My ISP
13.06.2019 · What is Double NAT Upstream NAT Integrating an OpenWrt network device in your network If you want to have an OpenWrt-powered network infrastructure, there are good chances you will need to reconfigure (or replace) the device the ISP gave you to access Internet.

Jun 13, 2019 · Double NAT also screws up communication between devices connected to the upstream device (the device provided by the ISP) and the downstream device (the OpenWrt router). What is NAT In a typical home network, you are allotted a single public IP address by your ISP , and this address gets issued to your router when you plug it into the ISP ...
Sep 28, 2020 · Cable Router 192.168.0.1 <-> OpenWRT Linux router, 192.168.0.2 (WAN), 10.0.0.199 (LAN) <-> LAN 10.0.0.x. So I am using double NAT, masquerading the WAN port of the OpenWRT router. The issue now is, that downloads randomly slow down on all Windows clients after a few seconds. Starting at max speed of 500mbit and then slow down rapidly to around ...
Getting rid of the double NAT is going to be easier than trying anything else. I'm guessing you have your own wireless router connected to your ISP's wireless gateway (aka modem). You'll need to bridge the gateway. Look up the manual or Google instructions for bridging the modem.
To deal with this double NAT problem and use IPv4 as flawlessly as possible, you need to choose how OpenWrt gets connected on its upstream side from several options. Note that in all these examples, the OpenWrt device is assumed to be on the “inside” of the network, i.e. clients ↔ OpenWrt device ↔ ISP device ↔ Internet.
OpenWrt as cascaded router behind another router (double NAT) Device as router, internet ISP device as modem-bridge Device as double-NAT router with DS-Lite Device as router with disabled NAT, additional routing rules Device as router as "exposed host" in the ISP router Device as router in an ideal IPv6-only configuration
NAT Reflection in einer Double-NAT Konfiguration mit OpenWrt Wenn das vom Internetservice-Provider bereitgestellte Modem keinen Bridge-Modus unterstützt, lässt sich ein eigener Router nur im DMZ betreiben. Dabei erfolgt allerdings bereits ein NAT und der dahinterliegende Router bekommt keine öffentliche IP-Adresse mehr zugewiesen.
