I want to thanks all that helped with the setup of my vultr vps with BGP and openvpn to distribute the /24 that was assigned to me. I played a lot with the openvpn and wireguard software up to a point I had to redo the whole install of the VPS. here is the receipy I have been able to use for the task. I am running a Debian10 that was updated to the latest software First I have use the tutorial at https://www.vultr.com/docs/configuring-bgp-on-vultr Be aware that on my version of bird I was not able to open the "/var/log/bird.log" files because of a propriatary right. the file belongned to root and it was supposed to belong to bird it is a known bug that I hope will be fixed soon. this helped me create that information into my bird.conf ------------------------------------------------------------------------------ log "/var/log/bird.log" all; router id xxx.xxx.xxx.xxx ; use the ipv4 address assigned to your vps protocol device { scan time 60; } protocol static { route 44.xxx.xxx.0/24 via xxx.xxx.xxx.xxx ; use your assigned /24 from ampr and the ipv4 from your vps } protocol bgp vultr { local as yyyyyyyyyyy; this is the private asn given to you by vultr and availble on your dashboard on myvultr.com for your vps source address xxx.xxx.xxx.xxx; import none; export all; graceful restart on; next hop self; multihop 2; neighbor 169.254.169.254 as 64515; password "YourSecretPassword" ; } ------------------------------------------------------------------------------ On the openvpn side of thing I have use the install script from angristan available at https://github.com/angristan/openvpn-install just followed the instruction and all was good. from there I changed some things on my network at etc/network/interfaces -------------------------------------------------------------------------- # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). #source /etc/network/interfaces.d/* auto lo iface lo inet loopback auto ens3 allow-hotplug ens3 iface ens3 inet dhcp iface ens3 inet static address 44.135.59.1/32 --------------------------------------------------------------------- the last line point at the first address of my /24 put yours into your file. then on the openvpn server I changed into the server.conf file only one line the file is at /etc/openvpn/server.conf i switched the server line from server 10.8.0.0 255.255.255.0 to server 44.135.59.0 255.255.255.0 the 44 address is my /24 put yours if you follow my exemple. that's it! it was not that complicated. But I had to dig a bit to understand the whole thing. My next step will be to split my /24 in parts. one section will be for the single connections like now, but I want to have connection that are like blocks of /28 or /29. I know I will have to make another instence of the openvpn server That is the part that is the less clear for me yet. The conf file is more clear. As I want to strat and stop each instence easily I will have to make a new starting script for systemd And that is where I will need to read more. If this helps someone I will be happy! If you see a problem with my setup please let me know!
