1. How does a fixup protocol command know when to open a conduit for an inbound connection?
2. My UNIX administrator has asked me to allow rsh access through the PIX Firewall to administer servers from home. Is this a good idea?
3. If the fixup protocol rtsp 554 is disabled by default, why are my users able to view content?
4. I'm planning to install a PIX Firewall, but I've heard that the MailGuard feature is incompatible with Microsoft Exchange Server. What can be done to overcome this?
