i've following setup:
openwrt router:
fixed ip address 192.168.1.1
mobile phone (+usb-c/ethernet hub) acting as internet modem connected to router wan port
ip address 10.42.0.1
linux machine:
fixed ip address 192.168.1.31
default route 192.168.1.1
dns AUTO
Local browsing is ok, but internet browsing work just if i set dns to MANUAL 10.42.0.1
How do I set router to work with dns AUTO and allow internet browsing?
thanks in advance
you have a cell phone with an ethernet port ?
yes, its an hub usbc-ethernet
OK,
then post your /etc/config/network
If you connect a client directly to the phone, does internet work ?
direct connection works.
here is
cat /etc/config/network
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd12:473d:467f::/48'
config interface 'wan'
option device 'eth0.1'
option proto 'dhcp'
config interface 'wan6'
option device 'eth0.1'
option proto 'dhcpv6'
config device
option name 'br-lan'
option type 'bridge'
list ports 'eth0.2'
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '0 8t'
config switch_vlan
option device 'switch0'
option vlan '2'
option ports '1 2 3 4 8t'
not a solution, but a work around, use the 6 option from https://openwrt.org/docs/guide-user/base-system/dhcp_configuration#dhcp_options to provide your clients with the DNS IP of the phone, or some other DNS, like 1.1.1.1.
you can also check if adding nameserver 10.42.0.1 to /etc/resolv.conf works.
ciao frollic,
i sent via terminal following command:
uci add_list dhcp.lan.dhcp_option="6,10.42.0.1"
uci commit dhcp
service dnsmasq restart
rebooted router, I still have same issue.
this also doesn't fix the issue
Let's see the following:
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:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
Also, from the router itself, please run some ping tests:
ping 8.8.8.8
ping 139.59.210.197
ping forum.openwrt.org
Then repeat those tests on a computer behind the router.

Great... so the router itself is working. What about the a device behind the router?
it's a mobile phone connected to the wan router ethernet port througth an usb-c ethernet hub
ok... do you have an app on that device for ping and/or traceroute? That will be really helpful.
no app, no GUI configuration, as far as I know is "trasparent" for the traffic
Sorry... I got confused...
re-reading, I see that the mobile device is the upstream connection.
Please test from the linux box.
this is from linux box

ok... so this is clearly a DNS related issue that we see only on the downstream device.
