Hello,

I haven't found anything about setting up external IP on a virtual host. I have comcast business service, they provide 5 static IPs.

How do I setup external IP on a VM?

My PROXMOX internal IP is 192.168.1.100 and that works fine.

I want to use this one debian VM with ISPCONFIG3 but I need external IP setup so this VM can be accessed from outside.

Thanks.
:confused:

Hi,
it's depends on your network config. How do you reach the ip-range of your external IPs?
The easy way is, if you have a single interface for that network (like eth1). Then you can install a new bridge (vmbr1, or what you like) with the eth1-nic connected to this bridge. The host don't need a ip on this bridge.
Then select the new bridge for the nic of the VM - and you are accesible from outside.
If you get all over one nic (without vlan-tagging) ask your provider, or look for the example in this forum for hetzner (i think they do also such things).

Thanks Udo, I searched thru forum some more, I was able to setup public IP for PROXMOX and one of the VMs. Thanks. Here's what I did, it worked.

PROXMOX
/etc/network/interfaces

Code:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
        address  0.0.0.0
        netmask  0.0.0.0

auto vmbr0
iface vmbr0 inet static
        address 75.111.111.10
        netmask 255.255.255.0
        gateway 75.111.111.15
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
VM101
/etc/network/interfaces

Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 75.111.111.11
        netmask 255.255.255.0
        network 75.111.111.0
        broadcast 75.111.111.255
        gateway 75.111.111.15
