restart the service. Reload, in this case, is probably not sufficient. Make 
sure iptables allows traffic through that port. If you run "iptables -L" and 
get a list of ports that are open then you are most certainly blocking that 
port, unless you have already configured iptables to allow traffic to the 
port.

The ssh configuration is pretty straight forward. The only mistake I can see 
someone making is confusing the client configuration file "ssh_config" with 
the daemon configuration file "sshd_config".  

try "ssh -p 22 user at server" and see if ssh is still listening on port 22.
from the server try  "ssh -p 3022 user at 127.0.0.1".  Localhost is usually not 
firewalled, and sshd by default listens on all interfaces including the 
loopback device.

a) sshd is running on the old port 22 because the service has not been 
restarted

b) the new port is firewalled.

c) sshd is not running "ps -A|grep sshd"
