This will probably work if you rm /overlay/upper/etc/config/firewall to restore the firewall to default. The changes you made there are all messed up. The default firewall has two zones for the networks lan and wan and proper forwarding out to wan. So if you don't by default get a wan network in /etc/config/network, create one named exactly 'wan' and it will match the firewall.

Also check that port 3 on the switch is the one that you are plugging into the modem/router. The numbers on the case may not match the numbers in the config.

Can you ping 8.8.8.8 from lan device?

i was using lan3 port i found lan4 port is the wan port i reconfigured settings as basic toturial setting wan ip as client to adsl router 192.168.1.200 /255.255.255.0/192.168.1.1/dns servsers and making lan ip as 192.168.2.1/255.255.255.0/192.168.2.1 enabled dhcp for lan only and connected cables the right way . now i am connected to internet but not briged

note : i use pulpstone lede 17.1.4 which has lan4 port is wan by default
