Topic: Problems about network

The content of this topic has been archived on 29 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I have a problem. In the Page  Status>Overview:network, why just the IP WAN status show the status of br-lan? Some wrong configuration ?

Yes. You most likely have a redundant "option gateway" on your lan interface. Remove it.

Ok, let me explain this precisely. If I set the gateway of lan  to any address, the wan (in the Status>Overview:network) will show the br-lan status, including setting it to itself. By leaving it out, the overview shows nothing about br-lan. But no matter what I set it , the default gateway of the connected client  will be not changed just the address of lan.  How could this happen?

By adding "option gateway" to the lan you effectively isntall a 2nd default route which will confuse LuCI. You usually should have only one default route which is pointing to the wan interface.

Yeah, I think so. Thank you for your answer. But The odd thing is the page structure of WAN and LAN are the same. There is a gateway input text frame in the LAN page. It is normal?

Yes. Lan and wan are just names on openwrt, in contrast to other firmwares where they're treated sepecially in the gui.

Thank you so much for your time.
