    Default rtsp announce to WMS with port forwarding/NAT

    We have multiple rtsp encoders behind a NAT that will announce streams to a WMS. How can I tell WMS to use a forwarding port instead of 554 to pull a streams from clients?

    Wowza can pull a rtsp stream over any port as long as it is not blocked by a firewall and is properly mapped in your network to the Wowza server. Take a look at these guides:

    Thank you Richard, but I assume you missunderstud me.

    Our rtsp encoders are behind a NAT and can reach WMS with rtsp ANNOUNCE. Later if one of these encoders will be requested the WMS should establish a new rtsp session to pull these streams from the NATing router with port forwarding. But how can I tell WMS to use a specific port for NAT traversal? (WMS and NAT have public IP, but dynamic changes, so it cant be configured in WMS)

    enc1 -- \
    enc2------- NAT -------------------- WMS <---- webclient
    enc3---/

    Announce1 --------->
    Announce2 --------->
    Announce3 --------->
    Announce4 --------->

    <------- PLAY <NAT-IP>:55544 stream 3

    Can I put something in the SDP part of the ANNOUNCE msg which let WMS use another port then 554?

    Thanks in advance - Sascha
