For enterprise networks where Internet Protocol security (IPsec) (see IETF RFC 4301-4309) has been deployed, IPsec must be disabled over the range of ports used for the delivery of audio, video, and panorama video. The recommendation is motivated by the need to avoid any delay in the allocation of media ports due to IPsec negotiation.

The following table explains the recommended IPsec exception settings.
