Whether A and C IP is not on A network segment, and there is no match to C on A network segment of routing? Their best IP configuration (IP, mask) send it together,

With double card machine before I had such a phenomenon, the reason is the default routing problem,
1, modify A machine's default routing, check the routing table
2, the route del default gw 0.0.0.0 to delete the default routing
3, and then configure the IP address of the according to you add a new default routes
