ICMP Redirect force to change the routing table
03/26/2020 10 10517
ICMP Redirect is a mechanism to convey routing information to hosts. The message informs a host to update its routing information (to send packets on an alternative route).
If for a specific reason there is the need to disable the ICMP Redirect option on the LAN Zone follow the instruction below:
Firewall Settings | Advanced, disable the option “Enable ICMP Redirect on LAN zone”.
Now the ICMP Redirect should be disabled on the LAN Zone.
