I apologize for any confusion caused by my slightly ambiguous language. In both cases, I was referring to the DHCP address/subnet assigned to the OpenWrt router's WAN port, by the ISP's gear. This will be an RFC1918 address by default.</div><div><br class=""></div><div>But my point is that the OpenWrt router has no way to predict what address/subnet will be assigned to its WAN port. Consequently, at boot-time, OpenWrt should simply choose some different subnet for its LAN subnet(s), and then advertise an mDNS name.</div><div><br class=""></div><div>Does this make sense?
