I have several VPNs against AWS, it happens that at random the traffic falls and come back again .sometimes I have to install policy to make come back again
it was with 5900 and 80.10 , and now again with a new 6700 and 80.40
what I see in the logs:
IKE_NAT_TRAVERSAL Traffic Dropped from aws to cp
"Packet is dropped because an IPsec SA associated with the SPI on the received IPsec packet could not be found"
"Unknown SPI: 0x8799740b for UDP encapsulated IPsec packet"
any idea? cp tech are trying to resolve it for a long time
