I'm trying to capture some incoming HTTP connections with Wireshark
0.99.8 on a Windows Server 2003 system. The only thing Wireshark
captures is the three packets in the three-way handshake of the TCP
connection; no other packets related to the connection are captured.
However, the connection completes successfully. No capture filter is
active in Wireshark.
When running Wireshark on the PC that originates the connection, the
entire transaction is successfully captured on the originating PC.
When the connection originates from a PC on the same LAN as the
Windows 2003 Server system, Wireshark on the Windows 2003 Server
system successfully captures the entire transaction.
The problem only occurs when the connection originates from the
Internet. The LAN in question has a SonicWALL firewall with no
special configuration.
What could cause Wireshark not to see the entire connection?
