How is ICMP redirect enabled?

-

a 2012 server not adding routes routing table.  sonicwall sending icmp redirect packets , firewall allows icmp redirects.  in fact setting firewall allow doesn't fix it.

performance monitor shows icmp redirect packets arriving on server.

so why isn't route being added route table?

hi,

windows nt specifics:
host route learned means of icmp redirect added route table 10 minutes, after time removed , must relearned through icmp redirect.

this described in kb 195686
