Leaving out the IP address serves no purpose and without a) the IP=20
address(es) and subnet mask(s) of the host this message comes from and=20
b) the IP address that causes the message, you are simply asking us to=20
be psychic.

However, here is the scenario which has caused my machine to generate=20
these messages:

1) External address assigned by DHCP from a cable modem e.g. 82.50.100.10=
1
2) My internal network address 192.165.5.1/255.255.0.0
3) Cable modem itself insists it has address 192.9.100.1

Address 3 is accessed via address 1 (the external interface) but has an=20
IP address consistent with being on the internal network, hence the messa=
ge.
