Yep. I was going to make the same comment to Ian (a NAT can't treat  
DCCP like UDP *and* TCP, because the timeouts are usually very  
different).

That'd be my expectation as well. As a datapoint, do we know what  
timer the Linux NAT code uses for DCCP? (And if we know of other NATs  
that translate DCCP, do we know their timers?)
