Hi,
What the capture shows is that you are not receiving IP traffic at all from remote hosts.
You are seeing retransmission because your computer tries to connect to a remote host through TCP but the remote host does not answer so you computer keeps trying. These extra trials are seen as retransmission by Wireshark.
In VPN jargon, it looks like Phase 1 is up but Phase 2 is not working.
I would suggest you check remote router for any sort of policy configuration.
Somewhere you configure the allowed IP addresses or subnets for instance.
Hope this helps.
Cheers,
JFD
