3G connection Sharing

Hello everyone,

I would like to share the 3G connection of the module (rmnet0 interface) over usb0 or eth0 interface.

My first idea was to setup a bridge but rmnet0 interface cannot be added to the bridge.

Any idea how to do this?

Thank you very much for your support

Hi,

You can try this:

iptables -t nat -A POSTROUTING -o rmnet0 -j MASQUERADE
iptables -A FORWARD -i rmnet0 -o usb0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i usb0 -o rmnet0 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward
