Hi, I am openBSC version 0.9.11.92-6d42 and I have compiled open-ggsn and the osmo-sgsn binary has been built when i recompiled openBSC. Now here is the problem. The GPRS indicator on the handset lights up, but no GPRS data passes. I have the following config files:
---------/etc/ggsn.conf---------
# TAG: listen
# Specifies the local IP address to listen to
listen 192.168.1.70
# 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

I have setup the server to have 4 virtual addresses: 192.168.1.50, 192.168.1.60, 192.168.1.70, 192.168.1.80.
When I start the ggsn and do a route -n it shows thats tun0 is up with the ip range 192.168.0.0/24. I have specified it to be 192.168.1.254 via the dynip argument in the /etc/ggsn.conf file. I have setup iptables to NAT eth0 so no issues there.
Thanks

Hi, I am trying to punch a nanoBTS through a firewall to an instance of openBSC over layer3. I have opended TCP port 3002 (OML) and TCP port 3003 (RSL) but no green light or any traffic captured with tcpdump. Any ideas? I havent changed the default port on the bts.
hello
one of my bs11 ist set to 30mw, the other one to 2w, bs11_config told
me. this is to much. how do i get the 2nd downto 30mw?

Hi ,
Here i want to restate my problem. I want to run two different bts with
different network parameters on the same PC, at the same time. I can not
achieve this with one bsc_hack because bsc has a unique mnc. I can not run
two bsc_hack at the same time because they try to use the same port. I think
that there might be two approaches to solve this:
1) Modifying the code such that i can specify different mnc for each bts
with one executable program. Maybe, two different gsm network can be defined
as network1 and network2 (similar to bts0,bts1,...). So i can give different
network parameters for different networks and run them with one program.
2) Changing the communication port of nanoBTS and OpenBSC such that i can
run two bsc_hack at the same. I think that it should be changed on both
nanoBTS and source code.
Could any one help me (at least give some hints) about how i can implement
one of these approaches. Or, You could propose some other approaches.
Thank you.
Jason
