My client has an existing PIX-PIX IPsec VPN between their offices thoughout the world. They wish to start using a video conferencing application that multicast the video streams to interested parties. I read somewhere that a PIX will not pass multicast packets. My questions therefore are thus:
1. Does this mean that the VC will not work with the current config?
2. If the answer to question one is that network config needs changing then does anyone have any ideas how to get around this problem?
