Ok. I was stupid (again).
It wasn't a networking issue, as I was able to login as root once I changed
PermitRootLogin to yes. So I started looking at other things, and discovered
that when I created the user, I did not specify the login shell. Therefore, it
was set as /bin/false instead of /
I'm having problems using ssh to log into a zone as a user. I can sftp into
it, but not ssh. It asks for my password, and then once I enter it, it
immediately closes the connection.
I'm using IPFilter's NAT capabilities to port forward.
In my /etc/ipf/ipnat.conf file. I have:
rdr routert3.vn
