OpenVPN with two IP public

[hack3rcon]

Hello,
Suppose you have an OpenVPN server. Now, you want to set two public IP addresses on it. Your public IP addresses are:

1.2.3.4
1.2.3.5

Your OpenVPN server has one NIC as below:

# ifconfig
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.2.15  netmask 255.255.255.0  broadcast 10.0.2.255
        inet6 fe80::a00:27ff:feed:b47c  prefixlen 64  scopeid 0x20<link>
        ether 08:00:27:ed:b4:7c  txqueuelen 1000  (Ethernet)
        RX packets 14915  bytes 2455731 (2.3 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 11701  bytes 1581492 (1.5 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 4  bytes 336 (336.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 4  bytes 336 (336.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Can you show how to prepare your OpenVPN server step by step? For example, You must first create a virtual network card and assign the IP addresses to it then…
The goal of this project is that you want different users to connect to different IP addresses.

I’m sure this thread is very useful for many users.

Thank you.
