Well It looks like I still have a problem.
When I connect to my openvpn server it works. BUT I have no connection to the outside
world.
here is my output of my iptable.
iptables -L -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
1937 332K ACCEPT udp -- ens3 any anywhere anywhere
udp dpt:openvpn

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)

979 94816 ACCEPT all -- tun0 ens3 anywhere anywhere
0 0 ACCEPT all -- ens3 tun0 anywhere anywhere
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
and here is my network adress state:

Objet : BGP/openvpn finally all ok.
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!
