Two things concern me about this:
The kernel is using the same TCP port space for both IPv4 & IPv6. Isn't
this a change from prior kernels? Doesn't seem right to me. This would
have repercussions on things like masquerading unless it has finally been
changed to share the kernel's main port spaces.
Secondly, the server is complaining about the lack of listening sockets
even after setting one up for IPv4, which would be a bug in xtrans.
