WAN problem on local network

Installing and Using OpenWrt
#1

Hi all,

I have a Netgear R7800, before the WAN port was on LAN1, I wanted to put it on the WAN port, the only possibility for the cable to be recognized was to modify the switch. However, since I modified it, the internet is reaching the router but is no longer broadcast on my network. I enclose my differences config files. How can I redistribute the internet on my network? Thanking you for your help. Greetings.

You have both LAN and WAN defined on "eth1.1"; one should be on "eth0.1", and the other one on "eth1.2".

Thank you for your answer, I made the changes but I still do not have internet on my network.

Check the output:

ip address show; ip route show; ip rule show

You do not have a network mask on the WAN interface, and both LAN and WAN are on the same network segment. Perhaps you could explain a bit more how is this device connected to other devices.

Here is the diagram of my network, before connecting the internet to the WAN port it was connected to the LAN1 and it worked correctly, I had internet on my br-lan. My WAN network working without being configured in the router.
I know that this network is not done according to the rules of the art, but being inexperienced I tried to do as well as possible and functional, thing which was the case with which I change port. I tried to find a tutorial that suits my case but my search was in vain. Thank you very much for your help.

I isolated my problem, I wanted to use the WAN port for my network but for a silent access point it doesn't work, that's why I didn't have internet on my routers. Tomorrow I put my blah back on LAN1 as it was before. Thanking you for your help.

You're using it as a LAN device (dumb AP) so really you want all five Ethernet ports to be switched together as the same network. This is simple to do-- in the switch configuration move port 5 from VLAN 1 into VLAN 2, which becomes eth0.2 which is attached to the lan network. Then you can plug Ethernet cables into any port and it will work the same.

Do not create a wan network. The simple dumb AP (without guest networks etc) only has one network, the LAN.
