I'm not disputing that. When you start or restart a firewall it's common for
established TCP connections to be disrupted. That's perfectly normal and
doesn't require any changes to keep-alives etc.

What's more important is the question of whether the proxy was open, or
whether he simply failed to recognize his own IP addresses. People who
abuse open proxies aren't normally downloading bible-study material.

I was disputing "nothing to worry about".
