What does ping to www.google.de say?

It is possible that you need to enable ipforwarding in /etc/sysctl.conf…

If dns works on r4,look if client gets ip from r4,try pinging from your laptop connected on lanbr0…first lanbr-ip,then wan-ip,then your main-routers ip,8.8.8.8,and www.google.com

Possible you need static route on main-router for your r4 lan network,but i think it is not needed because you should have nat on wan,so your main-router should not see your lan subnet…only r4 wan ip

Now I’m connecting Main router to wan of banana BPI-R4

Boss so what I should do next to get the modem of 5G is working ?

Note : I installed Modem Manager package on the system

I did connected the Banana BPI from Main router and I tested the ping on each lan port (all same result)

root@bpi-r4:~# ping www.google.de
ping: www.google.de: Temporary failure in name resolution

frank-w · July 29, 2024, 8:44pm

Check ip forwarding:

cat /proc/sys/net/ipv4/ip_forward

And to enable forwarding:

sysctl -w net.ipv4.ip_forward=1

For modem i guess you need to add driver to kernel,but i do not know which…

First test if it is recognized by using lsusb (maybe you need to install usb-utils)

KFO · July 30, 2024, 4:38am

Dear @frank-w

Currently Network from main router To WAN Banana BPI R4

I enabled forwarding But still my laptop is not receiving network from Banana BPI R4 ………………………

When I removed the wan cable… that came from main router … To see if there is network from the modem but no luck

… In OpenWrt system I was using modem manager

I installed it on this system but i don’t know how control it … ?

Is there web interface? Can be installed from these packages to control the system?

_

frank-w · July 30, 2024, 5:30am

I do not have this modem…with mine i did some manual steps to get network connection.

I do not know any web interface like lucy as it is the best way to hack the router (my webserver is put into lxc container and blocked in firewall from external interfaces).

KFO · July 30, 2024, 5:57am

Is there any commands do you want me to use them and to install package for this modem …to run this modem

Im planning after this try to make video on YouTube to know how to use your system (frank system) to keep reference for other people

frank-w · July 30, 2024, 7:08am

as i said above you will need to add driver for this module to kernel, but first check if it is recognized correctly via lsusb

but i have only did some basic tests with my modem.

still have no ides why your internet does not work on your client

can you do

nft list ruleset
sysctl -p

on your r4? and try pinging vom your client to lanbr-ip,wan-ip,main-router lan-ip

KFO · July 30, 2024, 1:30pm

its =1 ( enabled)

but still no network on my laptop … when i’m connecting the main router to R4 and lan from R4 to my laptop

frank-w · July 30, 2024, 2:17pm

Ok,so no nat on wan, causing your main-router does not know how to send packets to your client…

Can you add route for your client subnet over r3 wan-ip on your main-router?

Alternatively you can try adding masquerade on r3 (hope command is correct…normally i load nft file)

nft add rule nat postrouting oif wan masquerade

ericwoud · July 30, 2024, 2:28pm

Is the nftables service started?

systemctl status nftables

systemctl start nftables

systemctl status nftables

nft list ruleset

frank-w · July 30, 2024, 3:03pm

It seems i missed to add the rules file…

KFO · July 30, 2024, 3:25pm

I formatted the flash and I burned the other image on it (I gave up from first file )

I burned the 2nd one on SD card

the 2nd one still there is no network on laptop but there is network on Router Banana R4

root@bpi-r4:~# cat /proc/sys/net/ipv4/ip_forward
1
root@bpi-r4:~# nft list ruleset
-bash: nft: command not found
root@bpi-r4:~# sysctl -p

All package updated … Ping to google is working

KFO · July 30, 2024, 3:34pm

Dude @ericwoud I added package nftables … by apt install nftables

ericwoud · July 30, 2024, 3:38pm

Like frank said, no rules file present

KFO · July 30, 2024, 3:39pm

So should I wait ?

can you advise me how to let system detect the modem …( because first time)

frank-w · July 30, 2024, 4:12pm

Oh…is nft missing? Try installing it via apt install nftables…and then run command i sent to add masquerade on wan

but i wonder why the service is there…

Uploaded a basic nftables rule file

KFO · July 30, 2024, 4:19pm

I did it and I did this also

but still no network on my laptop

frank-w · July 30, 2024, 4:20pm

does nft print any errors?

how does nft list ruleset looks like now?

oh i guess you need to create table and chain first

nft add table nat
nft 'add chain nat postrouting { type nat hook postrouting priority 100 ; }'
nft add rule nat postrouting oifname  wan masquerade

for modem please show output of lsusb and lspci (if this has pci-conection)

i found this patch [PATCH] USB: serial: option: add Fibocom FM350-GL

but have not found driver for it yet which needs to be enabled (with kernel recompile)

KFO · July 31, 2024, 1:47pm

Nothing Happened still no network… should I download the image again from your Google Drive

root@bpi-r4:~# nft add table nat
