Raspberry pi, wlan is serving a new subnet 192.168.100.0 lan is static ip on 192.168.1.100 and a separate router provides the internet
had to add a static route on openwrt for 192.168.1.0 and one on router for 192.168.100.0
(edit: only needed the return route on the router not one on openwrt for ping to work)
so on a device connected to wlan I can ping any device on 192.168.1.0 and 192.168.100.0 and dns lookup works but I cannot ping any device on internet such as 126.96.36.199
connected to openwrt via ssh on lan, openwrt can ping 188.8.131.52 OK
I reckon it is missing a default rule for wlan on openwrt how do I set this up
default via 192.168.1.1 dev br-lan
192.168.1.0/24 dev br-lan scope link src 192.168.1.100
192.168.100.0/24 dev br-wlan scope link src 192.168.100.1
sounds like your gateway needs to be told to NAT the non-local address range outbound.
sounds probable, I was expecting it to do that auto, but now you mention it maybe it only does it for stuff in the 192.168.1.0 range and the packets from openwrt to the netgear are in 192.168.100.0 range
not sure if can do that on a wnr2200 on stock firmware with the required precision, only on wan setup is a nat filtering option, secured or open
maybe need to rethink the topology and just hand out a reserved range in the 192.168.1.0 network to the openwrt wlan
unless it's like the double nat thing is the solution, masquerade on the openwrt router to the lan?
maybe I'll stick a better linux firewall router distro on the link to isp supplied router in modem mode..... then go all in and upgrade wmr2200 to openwrt...
