First time to Fedora so please be kind .....
I am trying to share my 3G network to the rest of my LAN and not having much luck.
My 3G interface is wwan0 set up by network manager and I get internet just fine.
I have my wired ethernet (em1) connected to a wireless router for the rest of the house ..
I have disabled em1 (wired) as a managed device in Network Manager else it just tries to use it as a primary interface and I have set it up to a fixed IP of 10.0.0.1, I have also set up and enabled dnsmasq to dish up 10.0.0.2 to .. 10.0.0.150 range.
I have then executed the following commands as root:
iptables -t nat -A POSTROUTING -o wwan0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
And then went into the firewall config to the masquerade setting and added the wwan0 interface and enabled it ..
However, devices plugged into the router do not get an IP .... what am I missing?
