[Config] IPSec VPN Tunnel subnet issue Hi, I am facing a weird issue. I have configured an IPsec tunnel between my 2 branch offices using Cisco ASA at both ends. The tunnel is establised and all the subnets on both sides are reachable. There are 3 subnets that I am reaching from location A to Location B.
Every now and then I am losing connectivity to only 1 subnet across the tunnel. During this time, the tunnel is still up and I am able to access the other 2 subnets. Only 1 subnet is not reachable and I am unable to find a cause for the same.
Any suggestions on what the possible reasons for such issues could be. As soon as I clear crypto, again all 3 subnets are reachable until the next time the issue occurs.
Got any logs from either device?
Also be helpful to have the configs (minus passwords) for review.
