My trace only shows inbound traffic.

Why can't I see outbound traffic too?

I have no filters in place and have selected all "real" (ie: non-virtual) interfaces. When I look for packets going FROM my ip address there is no data. I can see the other half of the conversation with the traffic coming in TO my ip address.

You'll need to add more detailed information (hardware & software) before this question can be addressed.

Are you capturing on Windows and do you have some endpoint AV or VPN software installed. If so then it is a common problem with some AV and VPN software, and you can either uninstall the offending software, or possible try the newer capture driver npcap (uninstalling WinPcap first).

That's interesting grahamb. The laptop on which I am having trouble does connect to the corporate WAN via a VPN gateway. The partner is on my local LAN outside the corporate WAN (i.e., not via the VPN). When I run wireshark on the local partner I see both inbound and outbound traffic. I suspect you have identified the root cause. I may examine the npcap option when I have some more time. Thank you.
