When there are ICMP unreachable errors, the associated FastL4/TCP connection is reset by the BIG-IP.
FastL4/TCP connection from the client to BIG-IP will be reset.
There is an end to end connection from a client to server via BIG-IP and there is an ICMP error from the BIG-IP to pool member.
None
Provide a DB variable "TM.FastL4_rst_on_icmp" which is enabled by default. When enabled, the connection will be reset on ICMP errors. If the DB variable is disabled, ICMP errors will not result in the connection being torn down by the BIG-IP.
