All:
This could be a known issue. I am fairly sure its due to traffic shaping being on. Also it appears to effect Debian boxes. if you ssh to it via ip4 after a minute or so ssh hangs and then crashes the session. Centos boxes not effected best I can tell. Debian's wiki gives this link https://wiki.debian.org/SSH#SSH_hangs
Possible cause
With some routers behind NAT and when using OpenSSH. During session setup, after the password has been given, OpenSSH sets the TOS (type of service) field in the IP datagram. The router chokes on this.
I was able to get past it with the resolution in the link.
Wanted to report for you all to know. I will do some more testing in the AM with Shaping off. If you all want any thing just hollar.
