[Winpcap-bugs] RE: [Wireshark-users] Starting Wireshark Capture BlocksNetworkTraffic

[MORSBACH, JOSEPH R (JOE), ATTOPS]

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?
 
Have a nice day

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!
