How you configure an OpenVPN server with two public IP addresses?

Post by hack3rcon » 2023/08/20 10:14:10

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

Code: Select all

1.2.3.4
1.2.3.5
Your OpenVPN server has one NIC as below:

Code: Select all

# 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...

I'm sure this thread is useful for many users.

Thank you.

And, a thread on Ask Fedora, and on Rocky forums. I'm going to lock this thread.
