Can't get portforwarding to work for Minecraft server

powerade661
Hello everyone,

I am trying to host a Minecraft server and I feel as if I have tried everything and you all are my last resort. I have No-IP as a DNS and have even set that up through Sophos however, no matter what I do nothing seems to work. Here is what I have so far.

    Hi, and welcome to the User BB!

    172.120.7.16 isn't an IP in 172.16.0.0/12.  Are you sure that's the address of your server?  If that's not the problem, try #3 in Rulz.

    Cheers - Bob

    According to the picture of the DNAT, the address of your server is 172.120.7.116.  That's outside of the private address space of 172.16.0.0/12 as specified by RFC 1918.

    Oh wow... Such a noobie mistake. I will change the address and report back to you. I didn't think about that, glad you pointed it out. The weird thing is, it works just fine on my wireless router's firewall when using port forwarding. Any ideas?

    Yeah that fixed it. I can't believe I did that after having gone through network+... -_- Thanks man I appreciate your time.

    Never mind. The server is able to be recognized however, Sophos immediately kills the connection when they try to connect. Any ideas?

    Why are you sure that the UTM is blocking? Might also be the server's firewall or similar.

    Any ideas?

    Yes: Check the logs (firewall, IPS)... [;)]

    Because as I stated above, it works just fine when using the router's firewall. That is why I know Windows Firewall isn't blocking the connection.

    As scorpionking suggests, try #1 in Rulz.

    Should I assume this to mean you have a router in line with your UTM? Are you double-natting? If your router has a firewall and a DHCP and your UTM also has firewall and DHCP that could explain why it's not working.

    I setup a minecraft server for my son and his friends and they're not having any issues accessing the internal server.

    Can you provide a little more info on your current configuration?
