Ping failed in Linux kernel 2.6.31
I have a problem and need some help.
In the Linux kernel 188.8.131.52 physical NIC ping virtual NIC timeout.
Roughly as follows:
installed the virtual NIC In the Linux kernel 184.108.40.206 .
The VPN connection ON/OFF is repeated a number of times in one day.
3G Network and NAT is uesd.
Use the 3G Network and Wired Network to VPN communication through virtual NIC.

Now, the following content is being investigated.
The problem of communication program.
The problem of driver.
The problem of operation system.
The problem of routing.
The problem of multiple drivers.
The problem of process.
