| This effectively disables NAT on the ISP router only for a single connected device on the ISP router downstream side: for obvious reasons, we will be connecting our OpenWrt router as this exposed host. So in the end, we have achieved single NAT solely in the network chain towards the OpenWrt router. | This effectively disables NAT on the ISP router only for a single connected device on the ISP router downstream side: for obvious reasons, we will be connecting our OpenWrt router as this exposed host.
