Ping firstly goes to the backnet interface

Incorrect interface priority
c:\>netsh interface ipv4 show interfaces Idx Met MTU State Name --- --- ----- ----------- ------------------- 2 10 1500 connected venet0 1 50 4294967295 connected Loopback Pseudo-Interface 1 3 10 1500 connected venet1
In the example above, venet0 and venet1 have the equal metrics but priority of venet0 is higher due to lower index.
The browser is firstly waiting for a response from DNS servers of backnet interface. When accessing a web site with a lot of attached redirection links it may not be displayed due to timeout.
