I have to disconnect LAN cable and reconnect it to get a valid IP address or issue a #ifconfig eth0.1 down then up.
Problem goes away if i reboot router with wan cable disconnected wait for router to load then connect.
When you reboot router with both wan and lan cables connected router's connected lans gets the ip address of the one behind wan cable, in my case took ip 192.168.0.1xx instead of(vs) 192.168.1.1xx but you don’t get internet access.
Something i noticed when i reboot router i don’t see the usual icon for searching for connection on my PC, cable shows always connected, maybe is something to help troubleshoot
And p.s there is nothing wrong with my bootloader because i tested various ones either oem bootloader nor custom compiled local one with latest sources makes the bug go away.

I think this is similar to the WAN-LAN leakage which has been addressed by the lzma-loader (https://git.lede-project.org/?p=source.git;a=commitdiff;h=b8730517068d6ab2850656220e5bf024ab25da83) for ar71xx.

I've tested CC today and have the leaking-problem.
Computer behind WT3020 got IP from router on Nexx's WAN port.

I ran into the same issue using GLI-MT300A, DHCP clients on LAN/WiFi got IP from router on WAN port.

Hi,
