It is very possible. If you can consume / view the rtmp stream originating from the vbrick, you can send it to Red5 using ffmpeg using this command:
ffmpeg -i rtmp://your.vbrick.ip/path_to_vbrick_stream -acodec copy -vcodec copy -f flv rtmp://your.red5.ip/live/vbrickstream
Obviously you can name the stream whatever you like and use any available app on your red5 server; I used "live" which is a default app. If your vbrick stream doesn't have audio, use this command instead:
ffmpeg -i rtmp://your.vbrick.ip/path_to_vbrick_stream -an -vcodec copy -f flv rtmp://your.red5.ip/live/vbrickstream
