I have many OpenVPN connections and mostly they can be connected at the same time using Tunnelblick. For multiple simultaneous connections, Tunnelblick will create different interfaces like "utun3", "utun4"
$ netstat -nr -f inet | grep tun
10.201/16 172.27.250.1 UGSc utun3
10.205/16 172.27.250.1 UGSc utun3
10.206/16 172.27.250.1 UGSc utun3
10.210/16 172.27.248.1 UGSc utun4
However, there are 2 OpenVPN connections, when connected one after another, only one "utun" is created. Although both shown connected in Tunnelblick UI, I can only access the first OpenVPN connected.
$ netstat -nr -f inet | grep tun
10.70/16 172.27.250.1 UGSc utun3
10.159/24 172.27.250.1 UGSc utun3
10.159.10/24 172.27.250.1 UGSc utun3
10.201/16 172.27.250.1 UGSc utun3
10.205/16 172.27.250.1 UGSc utun3
10.206/16 172.27.250.1 UGSc utun3
Apparently OpenVPN / Tunnelblick is treating the 2 VPNs as the same. Could anyone explain and how to fix it?
