[icmpv6-code]
An optional decimal number representing the ICMP code of the return ICMP packet. If the [icmpv6-
type] is [unreach], the code can also be one of the following pre-defined text codes:
ICMPv6 code Description
no-route No route to destination
prohibited Communication prohibited
scope-mismatch IP address scope mismatch
addr-unr Address unreachable
port-unr Port unreachable
For example, this rule causes the router to return an ICMPv6 Unreachable packet in response to all
IPv6 packets received on PPP 0:
bl ock r et ur n- i cmpv6 unr each i n br eak end on ppp 0
pass
Allows packets that match the rule to pass through the firewall.
