I have a nuk at adress 192.168.1.107
This machine run virtualbox, freepbx is on a vm at adress 192.168.1.182

I just want to know about the router forwarding port.
Must I redirect port to address 192.168.1.107 ie the “physical address” or the pbx adress ie 192.168.1.182.
Port redirected are 5060 for SIP and 10000to 10100 for rtp

Many thanks for your help

Just forward to 192.168.1.182 and it should work properly:

  1. The router ARPs for .182 and VB responds with the host (hardware) MAC address.
  2. Router sends packet with dest IP of .182 and dest MAC of the hardware.
  3. VB receives packet and sends it to virtual NIC of PBX.
