I have USB mobile Internet connection. I am able to share it but there is some small problem I like to find solution for.

I have a wireless router with 4 LAN ports. I shared my LAN connection eth0 and then cable connected to one of the LAN ports on the router. On the router I activate "Static Routing" and give the router the ip-address for my shared eth0.
The wireless network have different ip-address (my wireless home network).
This make me possible to share my mobile Internet-connection to other devices on my wireless home network.
But every-time when I restart my computer, other devices on my wireless network cannot connect to the Internet until I have change my wlan0 connection to hot-spot for short time (I wait until the connection will be active, then I can turn off the hot-spot, and the wlan0 can connect to the router again - to my home network). After I have changed my wlan0 to hotspot and back, other devices can connect to the Internet (for example Android phones), but before that, these devices are not able to connect to Internet, but of course able to connect to the router wireless network (my home network).

Of course I have no problems to connect to the Internet on my PC, that share the connection, but I am not able to connect other devices until I have turn on the hot-spot for just a minute.

Is it possible for me to do something so I don't need to make this step with hot-spot every-time, so after I turn on my mobile connection, all devices can just start using the Internet.
Why dos this happen, is it that the LAN connection isn't actually sharing the Internet-connection until finish this step?

I am using Linux Mint 15 "olivia" Cinnamon 64-bit

thanks.

I didn't see you mention forwarding. This is disabled by default. You can enable it for IPV4 as follows:

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

Thank you

Somehow things are working late yesterday and today. I didn't do anything so I don't know why. I will wait to see and if I get the problem again, I will do this.

I did open the "/proc/sys/net/ipv4/ip_forward" and I see it have "1" in it. That means it allow ip forwarding. I will look at it next time when I will not be able to connecting the Internet using my phone.

Thank you.
