Cool, I never heard of tcpflow. However, it appears this tool only handles tcp, not other transport protocols like udp, right?
Also, regarding icmp, although it is often blocked, you can modify the encapsulation so instead of ip->icmp, you can modify it such that it rides on udp.

Yea, in that case you should use tcpdump or something else. I just like the colouring.

Only what is absolutely necessary is let through by the firewall in my past experience. This includes disabling inbound UDP if the application does not need it. SYN scans work because you can poke the ports being used by the application.
For further actions, you may consider blocking this person and/or reporting abuse
