Minecraft Server Problems Ultimatum

[Slirth]

Alright strap in because I've searched everywhere on the internet to get this server working and nothing is working. Ok:

I set up my Forge server normally,
I port-forwarded my server on my Arris modem using the correct ip address,
gave my friends my public ip adress to connect,
it worked for a day, stopped working after a day because my ip address is dynamic,
tried setting up a static ip,
discovered this was not possible with my modem,

tried using hamachi instead,

i set up a network,

friends were able to connect to the hamachi network,

they were not able to connect to the MC server using the ipv4 address provided by hamachi,

I tried setting "severip=" in the server properties file to the same ipv4 address,

I received the "UNABLE TO BIND TO PORT" error,

I tried changing the server port in the server properties file to something else,

still received the same error,

I check my firewall settings in my control panel,

everything from minecraft to hamachi and java is allowed through,

I tried portforwarding and using hamachi at the same time,

still did not work,

 

I'm at a loss here people.

I would (in fact I did) just get a free dynamic DNS setup. http://www.noip.com lets ya get up to 3 for free, all you have to do is confirm you're still using it every 30 days.

 

I've seen hamachi mentioned before, but never used it, so no idea how to fix it.
