How can I reset all TCP connections on a particular VIP

IIRC, disabling the VIP would do it. If you simply want to delete them from your connection table, you can use the CLI for that...

You also *may* want to look at the 'reject' virtual server type, which does exactly what you want. I suspect that this may not be ideal for your use, but it's worth evaluating:
