SSH

On internal IP lets without problems.
Logs are empty for some reason (look at cat /var/log/messages | grep sshd )

Answer 1

Show the output of the commands:

netstat -ntpua | grep 2222
iptables-save
cat /etc/hosts.allow
cat /etc/hosts.deny

Answer 2

Most likely the problem is either in the firewall or in the routing, is your server by chance not behind nat?

Answer 3

As I understand it, you are a server behind NAT, forward port 22 (or which one you use for ssh) to the local address of the machine.
