In the deep end with a misconfigured network.

post #1 of 2
Thread Starter 
So for a while I have been learning about hosting things from a VM and recently jumped onto a server from OVH, cause it was reasonably priced. I opted for Proxmox cause it's easier and I like the web-ui. After receiving it I installed Mineos Turnkey 64bit on to a full KVM with a bridged network on auth0. Which is where things started going down hill.

I tried first by configuring the IPTables in Mineos. Testing the ports showed they were still closed, so I got on to the shell of my node and ran - ifconfig showing auth0 auth2 eth0
Where auth0 has the Ip configuration and eth0 is on multicast, but in proxmox eth0 is showing inactive while auth0 and auth2 are both active.

When I open up the mineos VM it's showing the correct IP while calling for eth0 as the network. None of the regular open ports are open for mineos from the internet.

So after searching for a very long time. I found some decent guides to follow... from 2009-2010.

http://myatus.com/p/guide-firewall-and-router-with-proxmox-extending-its-us/

I'm about to follow these to the dot to try and fix the network, I was wondering if anyone else has some relevant updated information for me before I do this. I've read through both articles and I understand what I'll be doing but are all of these steps up to date or the best option for having a secure/quick network? I'm using proxmox v3 for reference.

Thanks, hoping to put this small investment to work while learning something new.

Are you using SSH to ocnfigure teh box? Its allot easier! (when you learn how*)

When you are "openeing ports" are you sure there is a service listening on it
Code:
"netstat -anp | grep LISTEN"

Are you sure your iptables rule is correct? You dont need to know the interface as most vms only have one so just allow it all ;D
Code:
iptables -A INPUT -p tcp -j ACCEPT --dport 22  --source $i;

Are you sure that tehre isnt a rule blocking it?
Code:
iptables -nvL | less

ho0w are you using to test? Nmap or a "is this port open" service
