I am Suhendy, I am master degree student from university of indonesia
I have project to make GPRS private network using OSMOCOM

I have trouble in osmo-pcu which my log said like this

DLNS ERROR GPRS-NS2-VC(NSE01234-NSVC-UDP-0_0_0_0:23000-127_0_0_1:23000){BLOCKED}: Event RX-RESET_ACK not permitted (gprs_ns2_vc_fsm.c:937)

my osmo pcu make loop communication so my osmo-pcu and osmo-sgsn cant connect each other. 

this is my osmo-pcu.cfg
