Hi, I have installed on Centos the lastest Wowza version. In one interface I receive multicast video, this multicast has tagged with a VLAN from a private network, the server interface is tagged to join the multicast, in Wowza I do a transcoding from the multicast to RTMP to stream the video to a third party CDN, the RTMP should pass trough a second interface, this interface is the default interface who has the internet access.

How can I configure Wowza to stream the RTMP using the second or default network interface?

I checked other topics but I didn’t get resolve this issue
