Feb 16, 2017
- Cisco ASR 5000 Series
Known Affected Releases
Symptom: HeNB uses 4500 UDP port, during initial contact without NAT in between HeNB<->HeNBGW. Non UDP encapsulated Data coming from FAP tunnel will not get processed and will be dropped on SecGW. Conditions: When HeNB initiates SA_INIT exchange on 4500 UDP port and there is no NAT detected between HeNB and SecGW, then packets coming from FAP, which are non UDP encapsulated will be dropped on SecGW. Similarly, packets coming from SecGW/HeNBGW will be sent with UDP encapsulation towards HeNB, which may get dropped on HeNB.
