More config ...
= OpenBSC GPRS/EDGE Setup page =
Pre-requisites * A nano BTS with GPRS or EDGE support. BS-11 are not supported (yet?) * A compiled GGSN from OpenGGSN ( http://sourceforge.net/projects/ggsn/ ) * A working and up-to-date OpenBSC (see [wiki:Building_OpenBSC]) * You will need to (re-)build it after having installed OpenGGSN so that the libgtp is detected and the SGSN binary osmo-sgsn built.

=== OpenGGSN configuration ===
{{{- TAG: listen
- Specifies the local IP address to listen to
listen 192.168.1.129
}}}
- TAG: dynip
- Dynamic IP address pool.
- Used for allocation of dynamic IP address when address is not given
- by HLR.
- If this option is not given then the net option is used as a substitute.
dynip 192.168.254.0/24
- TAG: pcodns1/pcodns2
- Protocol configuration option domain name system server 1 & 2.
pcodns1 208.67.222.222
pcodns2 208.67.220.220
}}}
=== Network configuration ===
You will also need to configure some networking rules to allow connectivity from `tun0`. Look up linux networking/nat howtos on google.
The basic setup for testing only in a safe environment would be :
{{{
bash# echo 1 > /proc/sys/net/ipv4/ip_forward
bash# iptables -A POSTROUTING -s 192.168.254.0/24 -t nat -o eth0 -j MASQUERADE
}}}
(replace `eth0` by the interface providing your machine connectivity)
