| 2 | |
| 3 | FreeBSD support is experimental, please test and report bugs. The FreeBSD port is |
| 4 | tested on FreeBSD 4.x, but may also work on 5.x series. |
| 5 | |
| 6 | 1. Compiling |
| 7 | |
| 8 | You will need GNU make installed, standard BSD make will not work. |
| 9 | Everything should be straight-forward, run ./configure then gmake. |
| 10 | |
| 11 | 2. Kernel tuning |
| 12 | |
| 13 | Your kernel needs to include tun driver (GENERIC kernel does), make sure your |
| 14 | kernel config file contains the line |
| 15 | |
| 16 | pseudo-device tun |
| 17 | |
| 18 | or load the tun kernel module manually by issuing "kldload if_tun" as root. |
| 19 | OpenGGSN doesn't try to load the module itself right now. |
| 20 | |
| 21 | Also make sure your kernel has IP Forwarding enabled (it is not by default). |
| 22 | Add the line |
| 23 | |
| 24 | gateway_enable=yes |
| 25 | |
| 26 | to your /etc/rc.conf or manually issue "sysctl net.inet.ip.forwarding=1" |
| 27 | |
| 28 | 3. Known problems |
| 29 | |
| 30 | After ggsn is started, you have to manually add the route for your address pool: |
| 31 | |
| 32 | route add 192.168.0.0 -netmask 255.255.255.0 -iface tun0 |
