Single IP with multiple vms

[Joe_F]

I have 3 windows vms with one single shared IP address how do I setup the networking to share this address?
At the moment the virtual nic is showing but I don't know how to configure any of the rest of it.

AFAIU you mean you have one public IP an3 3 VMs which should have access to internet via that public IP.

Assign the public IP you have to host's physical NIC and create a bridge without physical NIC for being attached from the Windows VMs. After configuring this via GUI add into /etc/network/interfaces NAT (MASQUERADE) and routing enabled, see example at https://pve.proxmox.com/wiki/Networ...ith_tt_span_class_monospaced_iptables_span_tt

I have set it up in iptables, linked the vm to use it and entered the network config into the vm but it still has no network?

You must not forget to set the proper IP address default gateway in the VMs, in the above mentioned example it would be 10.10.10.2,3 etc. and 10.10.10.1

If these settings are correct follow the IP packets then by tcpdump respectively wireshark in Windows. If you make e.g. a ping from a VM to 8.8.8.8 it should start with ARP request for 10.10.10.1 an then send the ICMP message from VM to gateway which should forward it - after an ARP request to 198.51.100.1- to the internet router.

It just won't join the network.

 

[Joe_F]

I have imputed all the IP and DNS settings correct.

 

[Joe_F]

I also cannot get it to work either with a dedicated IP or sharing the hosts.

 

[Joe_F]

It is a hetzner dedicated server.

 

[Joe_F]

The interfaces file.

 

[Joe_F]

It was setup using your iso.

 

[Joe_F]

The host can access the internet fine

 

[Joe_F]

I fixed it by setting it to use the same Mac address as hetzner had provided.

or if you are on kimsufi hosting try this. I used this video to create vms on a local network and then forwarded only selected ports to each vm like one was a webserver to it got 80 and 443 another was a game server so it got 27015 etc very cool way to use only one public static ip and forward ports to local internet network via iptables thanks guys! https://www.youtube.com/watch?v=GBMbo4u8K1Q
