Try to 'telnet host port' through, assuming there is a listener at the target, and read the logs.

[root@RUVPN ~]# telnet 37.0.122.190
Trying 37.0.122.190
telnet: connect to address 37.0.122.190: Connection refused

You are forwarding port 23? S/b 'telnet host_or_ip 3074' ?

Correct me if i am wrong for the allow in iptables.
iptables -A FORWARD -p tcp -d 10.8.0.6 --dport 23 -j ACCEPT
iptables -A FORWARD -p udp -d 10.8.0.6 --dport 23 -j ACCEPT

No, the rule we are working on is 3074 tcp, and telnet can tcp to any port, optionally.

Now see if iptables on 37.0.122.190 logged a packet reject message.
