IP Forwarding on MangoH Red Board

mangOH Red
1

The MangoH red Board has a IOT Wifi module from Mirage and able to get the WiFI up.

Is is possible for Host PC to access internet from the IOT Wifi Module of the MangoH red board connected to it?

Can you please share the steps ?

2

Above is the step to share cellular data rmnet0 to pc usb.
Maybe you can do the same but change the rmnet0 interface to wifi wlan0.

3

MangoH red board comes up as enp0s29xxx on ubuntu PC.

So these are the steps on MangoH red board.

Wifi is connected using wifi client app.

iptables -A FORWARD -o usb0 -i wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT

iptables -A FORWARD -i usb0 -o wlan0 -j ACCEPT

echo 1 > /proc/sys/net/ipv4/ip_forward

On Ubuntu PC:

sudo route add default gw 192.168.2.2 enp0s29u1u4i19

Tried to Ping on Ubuntu PC, but get error “unknown host”

4

What is the ipaddress of enp0s29u1u4i19?

I suggest you sharing the cellular data to pc first to make sure everything is ok

5

i assign the ip address 192.168.2.3 to enp0s29u.

Is it mandatory to get the cellular data up on the Board ?

I have not inserted the sim card nor tested the cellular.

6

Just to make sure your setup is OK as the thread shows sharing cellular data to PC is OK.

7

i am able to get the cellular working.

Can you help me with steps for the wlan0 interface

8

You mean you can share cellular data to pc?

Can you help me resolve the cellular issue. I cant even ping from the MangoH red board

You meam cannot ping google server?
Then you need to use other sim card

Used a working sim. But no luck.

You mean the module cannot ping google server?

Thank you for this. Able to connect from PC to the wlan0 of the MangoH Red board.

There were few steps missing when earlier i tried this.
