Multimedia support in PIX firewall

[hyperknowledge]

Is the multimedia support funtion by default is on in PIX firewall? or I need to explicitly set the access list for the corresponding services?

I noticed there are 2 collection of protocols are supported by PIX firewall - RTSP and H.323. To allow multimedia support, do I need to add access-list for them? If I need, where I can find the RTSP? When I try to add access rules, in the service list, I can't find the RTSP.

ALso, to allow internal computers to use MSN services (include, audio and video http://www.microsoft.com/technet/prodtechnol/winxppro/deploy/worki01.mspx), do I need to config anything for the PIX firewall?

Thanks in advance

In this case, is MSN messenger support in PIX 6.2 (any configuration required?)
