Hi Neels,

Looking into your configuration, I managed to start sgsn,ggsn,nitb and pcu without error. However, When I look into the pcu running configuration I see that there is a different configuration from the starting one ( no egprs ), is this normal? I changed it to egprs. Another issue that I faced yesterday, was that I could connect my phone to the network (this one time, today I was trying to connect but it didnt connected), and the symbol of GPRS appeared, but couldnt make a ping to 8.8.8.8 for example, even after doing the nat masquerade thing.

I see in the vty sgsn that my phone does several routing area update, but does not connect. what it could be?

Here is my configuration attached, I am running everything on sysmo2050.

Best,

Marcus Dias

Hard to help with this little information.

I have attached a tar with scripts and configs I use to run voice and data on a
sysmoBTS. Note that this is a rather convoluted way that fits my personal needs
of development testing. Maybe you can figure something out from it...

Feel free to ask more specific questions here, including your config and error
symptoms.
