Display unwanted dial-out packets
A diagnostic option captures and displays packets that cause the Pipeline to dial
out. You can then use the information to write data or call filters to prevent the
packets from bringing up unwanted connections.
When packets are not captured
If a dial out is initiated for any of the following reasons, the wdDialout option
does not capture a packet:
• Dial out caused by the Ctrl-D user command
• Dial out caused by callback security
• Dial out on nailed channels
• Dial out caused by NAT (Network Access Translation) acquiring an IP
address
• Dial out initiated for IP over X.25, when the X.25 internet profile changes to
active and there is data waiting for X.25 to bring up the connection
• Dial out caused by IGMP (Internet Group Management Protocol) multicast
forwarding
• Dial out to acquire a DNS address during PPP negotiations
