In some cases a Linux terminal may report the following message repeatedly "<IP-Adresse des Routers> sent an invalid ICMP error to a broadcast". The solution is to enter the following line as root. More information can be found and to read through the MAN SYSCTL pages for more information.
sysctl -w net/ipv4/icmp_ignore_bogus_error_responses=1
