-- SYN/ACK packets arriving on a tunnel fail to be matched to an existing flow followed by a RST issued by the BIG-IP system. -- The BIG-IP system reports 'no flow found'. -- MAC addresses can contain random values, or fe:fe:fe:fe:fe:fe.
NATT/ESP tunnel flows can end with a RST reset.
-- Using IKEv2 with both NAT-T and interface mode. -- The BIG-IP is configured to use several tmm instances. -- The combination of IP addresses and port numbers result in distributing legs of processing one flow across several tmm instances.
None.
In the ESP proxy, The system now clears a bit in packet metainformation related to forwarding, so a decrypted packet such as SYN/ACK can reach the last tmm needed.
