How to use two or more openvpn clients at the same time?

Question

linux

I want to connect to several ip at the same time, for this I use the VPN Gate service and I have, for example, two configs.

First:

dev tun
proto tcp
remote 211.127.50.206 1603
;http-proxy-retry
;http-proxy [proxy server] [proxy port]
cipher AES-128-CBC
auth SHA1
resolv-retry infinite
nobind
persist-key
persist-tun
client
verb 3

Second:

dev tun
proto tcp
remote 219.100.37.24 443
;http-proxy-retry
;http-proxy [proxy server] [proxy port]
cipher AES-128-CBC
auth SHA1
resolv-retry infinite
nobind
persist-key
persist-tun
client
verb 3

When I launch the second client, the following error occurs (the first one running at the same time works):

ERROR: Linux route add command failed: external program exited with error status: 2

If it helps, then ifconfigthey ip routelook like this:

Answer 1

the dev directive should point to tap0 and tap1 in the corresponding configs
, and also, you need to look at the errors in the logs, /var/log/*openvpn* (as far as I remember, the log name corresponds to the name of the config file and / or the service that openvpn is running on)
ps write route for the subnets of the vpn provider so that the traffic of the second does not go through the first open vpn
