PPPoE connected but no internet

Installing and Using OpenWrt
1

Hello,

Fresh install configured pppoe and it's working ( got IP from ISP) and DNS resolution worked completely both in router and lan however there is no internet connectivity in both of them, any tips where to start troubleshooting?

Thanks

2

Name resolution requires an internet connection, so there has to be some connectivity...
Does "ping 8.8.8.8" work? Does "ping www.google.com" work? And "opkg update"?

3

that's what I meant by DNS resolution the first two worked and no for third

4

What is the output of

ip addr; ip ro list table all; ip rule show
traceroute openwrt.org

?

6

IPv6 works fine.
Try with IPv4 traceroute -4 openwrt.org

Both work fine on the router. What doesn't work on the router?

no internet in router (opgk update) or lan devices

Are you sure you have the correct time set on the router?

13

Wrong time should give a different error.
Are you certain that your ISP doesn't have any weird settings needed?
What is the output of

wget -O - http://icanhazip.com

and there is no response

15

the time in the previous command output is different from time zone set in LUCI, is it related?

16

With http the time doesn't matter. It would be a problem with https.
It is evident that something is blocking your http(s) packets and you should talk to your ISP.

Hi

could you please try

wget -4 -O - http://icanhazip.com

18

whatever you want counsellor

the same result

hmmm

is your firewall at default settings?
did you try to mess with some 80 & 443 port forwarding ?

as i see, icmp & udp is working fine, it is not related to IPv6
both v4 & v6 have same result

as @trendy say, maybe your ISP block http(s) traffic, maybe you need to login somewhere ?
or you messed up your firewall

Can you try lowering the MTU on your PPPoE connection? Try 1492, 1480, or even 1400 to see if that helps.
