I have run into a bit of routing problem using my Raspberry Pi with a Sierra Wireless MC7455 connected through USB.
I am able to get internet access to the Raspberry Pi but the Pi is not able to route that connection to my LAN side which means that anything that is connected to it locally does not have internet access.
Here is what my network config looks like for now:
root@OpenWrt:~# cat /etc/config/network config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fxxx:xxxx:xxxx::/48' config interface 'lan' option type 'bridge' option ifname 'eth0' option proto 'dhcp' config interface 'wwan' option proto 'qmi' option device '/dev/cdc-wdm0' option ifname 'wwan0' option apn 'data641003' option type 'bridge'
Also this is how I know that I am getting data through the cell:
root@OpenWrt:~# ping -I wwan0 www.google.ca PING www.google.ca (18.104.22.168): 56 data bytes 64 bytes from 22.214.171.124: seq=0 ttl=50 time=89.238 ms 64 bytes from 126.96.36.199: seq=1 ttl=50 time=80.653 ms 64 bytes from 188.8.131.52: seq=2 ttl=50 time=102.277 ms 64 bytes from 184.108.40.206: seq=3 ttl=50 time=118.494 ms 64 bytes from 220.127.116.11: seq=4 ttl=50 time=94.663 ms
Sorry I am a noob to this environment. Any help would be greatly appreciated.
