If this is a managed VPN Service AT&T should be able to decipher this issue, Also are they using a hardware VPN concentrator at work?

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?

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!

David J. Pruitt
