Ping queries (not) working?

Installing and Using OpenWrt
1

Hi All,

At present, my Pi Router has "br-lan" (192.168.1.30) on eth0 to my laptop LAN (192.168.1.100). Eth1 is a USB->LAN dongle at 192.168.1.25, and WiFi (wlan0) at 192.168.1.13. I can ping all those from both LuCI and SSH terminal on the laptop.

I cannot get past those to any other devices within the 192.168.1.xxx range that are on my main router. Is this normal? Does it mean my wlan0 is not set up right?

And I have attempted to switch my laptop LAN to the dongle at 192.168.1.25, but the connection goes dead. I have tried loading that IP through LuCI and SSH but it doesn't connect. Do I need some kind of bridge connection like eth0 has?

Thanks!

Is there a wan port on the pi, I'm asking, since you call it a router.

Sorry, lingo lapse! :innocent:

I'm trying to get my spare Pi (eventually) set up as a router. Once I figure out WTH I'm doing. :woozy_face: Currently it's just a Pi with OpenWrt installed on it. (1) RJ45 port, (4) USB ports, (1) internal 2.4g WiFi radio, (1) HDMI, (1) audio jack, and the power plug. I'm basically trying to get an understanding of how to set up the devices/interfaces so they work as expected.

Seems like swapping my cable from eth0 to eth1 wouldn't necessarily break things, but ... oop there it is...

Since they all belong to the same subnet (192.168.1.0/24), they must be bridged, otherwise a lan host will not be able to reach them. Or you'll have to change the subnet for the other interfaces and use static routes on the main router to point where the other networks are.

You cannot have a device connected to two networks on the same range.

How would one properly bridge a network device/interface?

Can you elaborate a bit for dummies? Does this mean changing from 192.168.1.xxx to something like 192.168.10.xxx?

You already have the br-lan, so add the other interfaces under it.

Either that or bridging the interfaces
