Description Tommaso Pecorella 2015-11-06 17:33:13 UTC

This happens both in IPv4 and IPv6.

E.g., the function
Icmpv4L4Protocol::Forward (Ipv4Address source, Icmpv4Header icmp,
                           uint32_t info, Ipv4Header ipHeader,
                           const uint8_t payload[8])

does not know the incoming interface.
As a consequence, the ICMP error message is forwarded to the "default" L4 protocol, which could be not the right protocol.
