Separating EPC and IMS on different machines #15

Closed BorjanEch0 closed 1 year ago

BorjanEch0 commented 2 years ago

I have tried to separate the open5gs core and kamailio ims packages on 2 different machines, but when i do so and try to call an UE i have the problem that caller id is lost and the call goes through as private number? Do you have any idea what could be causing this? I doubt in 2 things

  1. I am forgetting to change some component ip from 127.0.0.x to a lan ip i changed only pcrf.
  2. ogstun2 interface is on a different machine and i am using a static route on the ims machine to point all traffic to the epc machine( ip route add 192.168.101.0/24 via 10.0.20.12(EPC) and this causes confusion in the realms or makes the packets have the wrong address.

any ideas would be very helpfull. If this works i will release a guide and in the near future deb packages for ready setup.

@BorjanEch0 Sorry for the late reply. If you could also post the config file I can take a look and help in debugging
