The GTP kernel module needs to be told if it operates in SGSN or GGSN mode. grep for GTP_ROLE_SGSN in libgtpnl. I don't know all of the related functions off my head, but on the SGSN side you need to make sure to initialize the kernel GTP with GTP_ROLE_SGSN instead of GTP_ROLE_GGSN. -- - Harald Welte <[email protected]> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
