I have installed openvpn client on my pc (windows 7) and I have two tap network adapters. In this way I can open two openvpn connections at the same time. What I would like to understand is how it's decided each connection I open which tap adapter will be chosen. The first available network adapter is chosen or some other logic exists?

The OS will choose the route (and thus interface) with the lowest metric. To tweak which interface is used you can push a route with a particular metric; for example

push route "10.10.10.0 255.255.255.0 10.0.0.2 1"

from the man page

--route network/IP [netmask] [gateway] [metric]

  • And in the default case, with same metrics, i'm not sure which one wins. Maybe the first that appeared in the routing table. – LatinSuD Sep 09 '14 at 12:20
