I have 2 IPSEC servers and 2 clients.
Both 2 clients connect to both servers, so there are 4 sessions.
Some days ago, the network of the servers' IDC broke for several minutes.
Then the 2 servers send DPD messages to clients.
The clients received them and replied, but servers did not received the
Then the 2 servers shutdown the sessions.
So far so good.
However, the 2 clients still thought the sessions are good, and did not
send any DPD messages.
So there were mis-match between the servers and clients.
Any one know the possible reason?
Thanks in advance
