I have a strange problem. I have a PIX 515 at central office and a PIX506e at the remote office.
We have VPN site to site working.
When the VPN times out the VPN tunnel comes down.
The strange things is:
when i try to send a ping from the central office to the remote office the ping fails, however, a vpn is created (show crytpo isakmp sa).
If i ping from the remote office to the central office the ping works. After the this i am able to ping from the central office to the remote office.
I want to be able to start the connection from the central office. What is the problem?
