I can ssh/putty into the ubuntu server and start the server but when I connect it fudges up.

That's why you should use nmap to scan the ports or wireshark to diagnose the traffic!

If you think it is a server issue then check the configuration of your server (which I think you already did).

If it is a router issue, then turn the machine into DMZ (in the router) and check the firewall configuration again with "iptables -vnL --line-numbers" and make sure that RELATED and ESTABLISHED are accepted (in the INPUT table).

If you want to test fast and dirty flush the tables "iptables -F"

That's all I can help you with mate... I am ashamed and sorry that I can't do more, and for that I kindly ask for forgiveness!

Peace

Lol I'll scan with nmap now and post the findings. I'm not turning it into DMZ, last time I tried that I had to factory reset my router....
