Hi
I've installed a RAC 10g on RHEL on HP servers,2 nodes。The cluster is running in a separate subnet.
Problem
There is a router between RAC and other subnet. I can access the RAC in the same subnet(192.168.10.*), Public-ip and VIP work well. Recently I cannot ping Public-ip and VIP sometimes from other subnet, but I can ping the other subnet from Public-ip and VIP all the time, which means there is only one way between RAC and outside visitors. I don't think it's the network equipment problem beacuse the network equipment config didn't change, the other servers in the RAC subnet can be accessed from outside as usual. It seems like the router only shutdown the connection from outside visitors to the RAC.
I found the similar problem is Bug 13440962 - Different subnet failed to connect to vip after restart vip. But I've checked the log, there was no reboot record(either server or rac instance), no VIP failover problem, no IP confliction. The most reasonable fact may be RAC was wrong working in someplace.
The scenario:

VIP 192.168.10.14
