Some people use 11.x.x.x, others use other subnet numbers.
Determining "behind NAT" is flawed, the whole point is for
it to be transparent anyways.
Agree - but which is better - flawed and working or perfect and not?
I think you really need to bite the bullet and start working
now on proper NAT deployment for DCCP. In the time you spend
working on half-working hacks you can have most of the firewalls
out there fixed.
Disagree - I have no control over people's firewalls and I think I
could write this patch in a few hours. (Arnaldo could probably write
in 30 minutes!)
