[SR-Users] Kamailio with 2 Public and Private IPs- SIP Call flow issues

Hello, I have the following setup: Kamailio:   Public Interface 70.36.25.65   Private Interface 10.168.10.227 Freeswitch:    Private Interface 10.168.10.200 I’m routing calls from kamailio to freeswitch, but when I try to hang up the call the freeswitch sends the BYE to the public address(70.36.25.65) and not to the private address 10.168.10.227. 200OK and ACK work correctly. It’s only the BYE that has an issue. Showing INVITES: Client Invite: T 82.80.164.63:53871 -> 70.36.25.65:5099 [AP] INVITE sip:+972549428460@70.36.25.65:5099 SIP/2.0.
