Hello, I am beginner on OpenWrt. I would like to connect my PC OpenWrt like home router to my fiber optic internet. I have my IP address from internet provider (IP,DNS,Gateway). I have two LAN ports. I need first one use like WAN and second one like LAN connected to my (8 port Gigabit Zyxel switch and Archer C20 like bridge just for wireless) for distributing Internet trough it. I am try it myself but unsuccessfully.
Thank you very much for help.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

there was my ISP connection address
when I am configured wireles in the OpenWrt PC there was internet connection but not in the LAN
This looks like an address behind another router (ISP provided, for example). This will not work for a direct connection to the internet.
We need to take a step back -- what is upstream of your new x86 router? Is it an ISP modem or modem+router combo unit? or something else? Please be specific.
on the wall I have just plastic box, and there is input FiberOptic cable and output UTP cable with connector. When I am connecting any other router like tp-link on the end of this cable everything working well.
ok... it sounds like you have an ONT (optical network terminal) -- presumably it is purely a media converter (fiber to copper) and not doing any routing.
First, you need to fix your lan interface... remove the gateway and dns, and change the address to use the .1 address (this last thing isn't required, but it is customary)
It should look like this:
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.0.1'
option netmask '255.255.255.0'
option ip6assign '60'
Next, you need to create a wan interface. You said that you have 2 ports on your x86 router -- hopefully it will 'just work' like this:
config interface 'wan'
option device 'eth1'
option proto 'dhcp'
config interface 'wan6'
option device 'eth1'
option proto 'dhcpv6'
Then reboot your router, plug the cable into your x86 machine's other port, and see if it works.
thank you very much! I am going to try it
once again thank you very much! all working well
awesome!
