I got the rpi4b awhile ago in hopes of making it my new home router/gateway/ap/firewall/dhcp server. Discovered right away that OpenWRT provided no stable release. So I put that project on the back burner and set up a Linksys WRT AC1900 instead. I got impatient recently and decided to have a go at getting the rpi4 set up. Having problems configuring wulfy23's build on this device.
rpi4 is a test router hooked to my current OpenWRT LAN. I first tried a different build on this device, one I found at https://github.com/robcollins55/Raspberry-Pi-4-OpenWrt-Router-Custombuild. Almost everything worked well out of the box using that build except that the Luci web interface was inaccessible. I've also realised that, although the individual that produced that build said that he would be releasing a new build weekly, no new build has been made since end of Nov. 2020. So I'm considering that project moribund and decided to try wulfy23's rpi4 build instead.
After flashing wulfy23's (r15323) build I quickly realized a kernel module was missing for the USB/ethernet adapter I have and want to use for my WAN port. I was able to get and install that module, then configure eth1 to be the WAN port and dhcp client. So the device gets an IP on my LAN and it also will give out an IP on its LAN port (eth0, different subnet). Further, I can access the Luci web interface from the client connected to the LAN port. I can ping internet addresses from the rpi4 itself in an ssh session.
However, the rpi4 is not routing any traffic out to the internet from the client hooked to it. I have so far not discovered the setting(s) on the rpi4 that will allow it to route traffic, whether ping or http traffic, from the client out to the internet. Another problem, which may or may not be related, is that although wulfy23's build comes with an ap (ap101) preconfigured and I have it enabled, no SSID is being broadcast.
Any suggestions as to how I can get this device functioning as intended? I've got a few years of experience fiddling with OpenWRT and a few more with DD-WRT, but there is obviously a fair amount about configuring routers that I do not understand terribly well. Any help will be much appreciated.
PS I've done a number of reflashes after trying various configuration options. The current flash is pretty vanilla with minimal tweaking.
