Understood.

Some thoughts:
- Restrict the UDM to retrieving /robots.txt.  (Generally
innocuous/legal content and not too large?)
- Limit the UDM to retrieving 4500 bytes or so of data and then sending
a RST.  (Enough data to confirm max MTU frames can be received but not
enough to contain inappropriate or illegal content?)
- Send a RST after receiving a SYN-ACK response.  (Would be useful to
allow port configuration in this case to allow tests for filtering.)
