Here are the steps I followed to get the card working:
- Follow the steps on pages 21-22 of the Sprint guide.
- Setup masquerading on your Linux box. I used the command "sudo iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o ppp0 -j MASQUERADE". This will be different depending on your network configuration.
- And the final step that was somewhat hard to figure out was to setup IP forwarding. This was the magic trick to completing the whole setup "sudo sysctl -w net.ipv4.ip_forward=1". There appears to be several ways to make this work, but using sysctl was the only way I could make it work with my specific configuration.
- Bring up your connection with "sudo wvdial" and enjoy!
