Hello,
I have 2 ASA 5520 with 8.2(1) OS. WE have multiple L2L VPNs with our Customer. But we are facing strange issue with.
To avoid IP conflict, we allot /32 IP address to source NAT from 10.2.28.0/24 pool.
Randomly VPN communication stops, where as IPsec tunnel shows up but user can’t access Servers and on ASA logging, I can see the Syn request but timeout after 1 minute. I have checked configuration, routing, NAT but all seems fine. I tried to fluctuate the tunnel many times, clearing SA’s but all in wain. Then I tried manual failover at ASA, then communication starts but after some time it again stops. Then I have to failover again.
Can someone suggest if it’s a configuration or bug issue that particular version or any compatibility issue with AWS and ASA?
Thanks,
Rakesh Kumar
