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. Joe Morsbach Sr. Technical Specialist AT&T Integrated Mobile Services

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?

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! David J.
