I've setup 2 VPN connections and on the Dial-Out side I've set it to load-balance.

When for example I make multiple connections from one site to the other then both VPN tunnels are used.

But when I make on connection i.e. from 192.168.1.23 to 192.168.4.45 then only one VPN tunnel is used. Isn't it possible to use both tunnels?
