[ READ ME ]Hamachi? [ READ ME ]

I have my hotel setup right now, but I can't portforward for some strange reason. I tried it earlier today and it caused me to lose my internet for about 3-4 hours today. I'm scared to try it again right now. Would it be a good idea to host it hamachi? Can I use no-ip.org to host it?

Please comment/post on what you think I should do...

Thanks!

Do not host it on hamachi, try portforwarding again.
Free Help Forwarding Ports - PortForward.com for a step by step guide on how to portforward. :)

People still use Hamachi for retros? wat.
