You're definitely right about it being WinPCap... I get the
same result when simply running windump on that interface.. My situation
is a little different than the gentleman's that started this
thread..
1) I have NO software firewall running
2) I am using AT&T AGN client 6.3
When attempting to capture, I am capturing on the VPN
Interface... I can see the outbound packets but no responses come back... This
gives the appearance of network traffic being blocked completely because
applications are not getting their responses. Once I stop the capture,
normal operation resumes.

This is definitely a WinPcap issue and not a wireshark one
(wireshark receives packets from WinPcap).
I would say that either the Symantec firewall, the VPN client
or the AT&T ipsec client (is that an ipsec client or a firewall) are
interacting really badly with the WinPcap protocol driver.
Can you please try disabling the AT&T firewall? Also, from
which adapter are you trying to capture? The ethernet adapter or on the
VPN?

Subject: [Wireshark-users] Starting Wireshark Capture
Blocks Network Traffic
Hello,
I downloaded and installed Wireshark version 0.99.5 with WinPcap
4.0 and am trying to capture some detailed TCP/IP packet transmissions from my
client application connecting via DSL using VPN software to connect to a
remote server on my business WAN. Once I start the Wireshark capture,
all of my applications on the client side cannot connect to my work network
over the VPN connection. I am able to access other web sites not using
the VPN. Any suggestions would be appreciated.
Thank You!
