You would configure the -SGSN to use one fixed GGSN (sending to gtphub) and gtphub will resolve the -GGSNs once it has received the messages. So the SGSN may be behind NAT (add -"sgsn-use-sender" to gtphub.conf) and communicate to various GGSNs over a -single link to gtphub. - -I hope this helps to get you going. -Any suggestions/patches are welcome! - -~Neels - |
