Using Ubuntu 14.04 (up to date).
I'd like to use two VPNs (openvpn) a the same time.
LAN is: 10.1.1.0/24
The 1st VPN, homemade, is only routing the 192.168.1.0/24 network via the tunnel.
Routes table before VPN1 is started
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.1.1.1 0.0.0.0 UG 0 0 0 eth0
10.1.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
Routes table after VPN1 is started
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.1.1.1 0.0.0.0 UG 0 0 0 eth0
10.14.0.0 10.14.0.2 255.255.255.0 UG 0 0 0 tun0
10.14.0.2 0.0.0.0 255.255.255.255 UH 0 0 0 tun0
10.1.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.88.0.1 10.88.0.5 255.255.255.255 UGH 0 0 0 tun1
10.88.0.5 0.0.0.0 255.255.255.255 UH 0 0 0 tun1
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
192.168.1.0 10.88.0.5 255.255.255.0 UG 0 0 0 tun1
The problem is after starting the 2nd VPN (from PIA), which installs a default route, the 192.168.1.0 subnet is not routed anymore. (The rest is working).
For instance, doing a ping to 192.168.1.1 works fine until the 2nd VPN becomes active.

169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
192.168.1.0 10.88.0.5 255.255.255.0 UG 0 0 0 tun1
However, and this is what I don't understand, the 192.168.1.0 route is still alive, and is way more specific than the default routes. There doesn't seem to be any conflicting internal openvpn tunnel routes.
Is this 192.168.1.0 routing problem fixable, having the two VPNs running at the same time?
