Use your Raspberry Pi as WiFi router
Using this guide I successfully turned my Raspberry Pi with an Edimax WiFi dongle into a WiFi hotspot.
- setup customized hostapd
- setup dhcp server
- configure NAT
My network layout looked like this:
internet - router - Pi - tablet | |---- PC
Now the tablet is able to connect to the PC, but not the other way round. To fix this, add a route to the PC’s IP configuration:
ip route add -net $PI_NETWORK netmask 255.255.255.0 gw $PI_IP
$PI_IP with your own values.
