Re: Some unusual network features

I've got some theories, but I'm not sure how much I'm jumping to 
conclusions.

My guesses: 

1) A tarpit. 
2) Hosts behind a firewall with some kind of Layer 7 inspecting proxy.
3) A firewall with a munged NAT configuration.
4) Some combination of the above. 

Have you tried fingerprinting the IP stack? I wouldn't be surprised to
find a homebrew *nix security box or a Symantec box.
