I have got a temporary scenario where I need to establish a IPSEC VPN between branch ( cisco router) and HQ ( VPN concentrator).
The tunnel is established fine but traffic stops passing after some 5 to 10 mins. I have to manually clear the crypto session and then the connectivity is fine. For testing the above I am sending ICMP packets from branch towards HQ. I can see 'cryto isakmp sa' and 'crytpo ipsec sa' both active and fine.
Please guys share your thoughts on this !!!

Hi,
Make sure that lifetime matches on Router and Concentrator.
Here's a doc for troubleshooting on IPSEC:-
