Hi Avatli,

can you please explain what exactly you are trying to do?

What is your overall goal? Which software do you want to use as GGSN/P-GW?

In case you assume that GTP is symmetric and that you can simply establish GTP
tunnels with some command line tunnels between two linux machines: That's not 
the case.

GTP exists to dynamically manage [lots of] per-subscriber tunnels, all of which
are represented within one GTP "link" by the kernel GTP module.

You always need a userspace application implementing the control plane instance
(GTP-C v1 for GGSN, v2 for P-GW).  And even with that, it always only 
implements the
GGSN / P-GW side and not the SGSN / S-GW side.
