Estou tentando executar várias instâncias de openvpn ao mesmo tempo, todas funcionam bem executando uma única, mas eu gostaria de ter várias instâncias, uma de cada conectada a um host diferente e de lá ser capaz de usar o interface que eu quero.
Estou tentando assim:
France.ovpn
client
dev tun
proto udp
remote france.privateinternetaccess.com
lport 1190
resolv-retry infinite
persist-key
persist-tun
cipher aes-128-cbc
auth sha1
tls-client
remote-cert-tls server
auth-user-pass /etc/openvpn/piaauth.txt
comp-lzo
verb 1
reneg-sec 0
crl-verify /etc/openvpn/crl.rsa.2048.pem
ca /etc/openvpn/ca.rsa.2048.crt
disable-occ
lport 1189
rport 1198
|
sudo /usr/sbin/openvpn --config /etc/openvpn/France.ovpn --dev tun0

Depois disso, tudo está funcionando. Mas quando eu executo a próxima instância eu recebo alguns erros.

Aqui ip link e ip addr , ambos falham.

Eu acho que só preciso configurar algumas rotas, estou certo?
