Krijg je van je provider toevallig een 10.x.x.x ip nummer ?
Wat geeft ifconfig -a voor output ?
uitleg :
from the RFC:
5.3.7 Martian Address Filtering
An IP source address is invalid if it is a special IP address, as
defined in 4.2.2.11 or 5.3.7, or is not a unicast address.
An IP destination address is invalid if it is among those defined as
illegal destinations in 4.2.3.1, or is a Class E address (except
255.255.255.255).
A router SHOULD NOT forward any packet that has an invalid IP source
address or a source address on network 0. A router SHOULD NOT
forward, except over a loopback interface, any packet that has a
source address on network 127. A router MAY have a switch that
allows the network manager to disable these checks. If such a switch
is provided, it MUST default to performing the checks.
A router SHOULD NOT forward any packet that has an invalid IP
destination address or a destination address on network 0. A router
SHOULD NOT forward, except over a loopback interface, any packet that
has a destination address on network 127. A router MAY have a switch
that allows the network manager to disable these checks. If such a
switch is provided, it MUST default to performing the checks.
If a router discards a packet because of these rules, it SHOULD log
at least the IP source address, the IP destination address, and, if
the problem was with the source address, the physical interface on
which the packet was received and the Link Layer address of the host
or router from which the packet was received.
