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. -- - Harald Welte <[email protected]> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
