I believe I found the cause of the issue.
We are running CentOS 6 with FOG version 1.4.3
I was forced to restrict the iptables to not advertise NFS to the rest of our campus and only to our subnets.
In that process, I did not allow for iptables to allow lo (loopback, 127.0.0.1) to be accepted, which will also cause this error.
While I did allow for 127.0.0.1 being the source, which fixed nfs having issues with RPCBind, it does not solve the trying to submit a snapin to FOG as it appears to use -i lo interface path.
This issue should be considered resolved.
