Strange errors in my D-Link DI-634M router log today

[Don Naegele]

Hi.

I have a D-Link DI-634M router.

While in my log today I noticed tons of errors, but everything is working
perfectly.

I'm getting this every 3 to 7 seconds from 3 different IP addresses:

Dropped packet from 169.254.1.82 to 169.254.1.255 that was received from the
wrong network interface (IP address spoofing)

The 3 IP addresses are 169.254.1.146, 169.254.1.82, and 169.254.1.188.

A call to D-Link suggested someone was accessing my router such as a
neighbor. I don't think that's correct. I have WEP encryption set on all my
devices, with a password none one could guess. I changed my SSID to
something no one would guess. I have SSID broadcast disabled, and I use MAC
filtering to only allow devices I've put in the router.

I did have FIOS TV installed the other day and they installed a Motorola
NIM100 (Network Interface Module) in my home near the router. I'm new to
this and can't find a manual for it.

I'm a bit lost when it comes to it's MAC address and IP stuff. The bottom of
the NIM100 has a HFC MAC ID that ends in 87 and also says cLINK MAC ID and
ends in 88. Does this mean it has two MAC addresses? Should I have both in
my MAC filter list?

When I added both of those to my MAC filters in my router setup (and
temporarly disabled MAC filters) I noticed my DHPC server assigned 3 IP's to
my STBs (Set Top Boxes), so I wrote down those and added them to my MAC
filters section to be safe and re-enabled MAC filtering.

After all that stuff everything seemed to work fine. I was NOT seeing any of
these strange errors in my router log.

The only reason I even looked in the log yesterday was because our Xbox Live
connection dropped at noon and I was trying to look for errors in the log. I
then noticed the new errors.

So my point is I'm thinking these errors probably don't have anything to do
with my new NIM100, but i'm not certain. I'm so new to networking that I
understand VERY little.

I'm a bit nervous about calling FIOS since they do NOT want people using
their own routers even though many online say they do just fine.

I'm so lost and feel that D-Link support was 'blowing me off'. It was
suggested initially that my network was unsecure and he lead me through
securing it, to which HE found out it WAS already secure.

Help.

I'm lost.

Don


p.s. Pardon the multiple posts. I'm not sure what newsgroup to ask for
help in.

Hi.

Someone suggested that I disconnect my devices one at a time to see if any
specific one was causing the error message.

I started with the new Motorola NIM100 and rebooted the router. I had NO
error messages. I then reconnected the router and didn't even reboot and
the error messages started.

So, what now?

I'm thinking making a call to Verizon will only result in them telling me to
use THEIR router.

Hi again.

I did some testing.

I kept the NIM100 connected, but then disconnected all 3 STBs. No errors.

I then reconnected the first STB and was getting one error with an IP ending
in .82.

I then reconnected the second STB and was getting two errors. The first
with .82 and now the 2nd adds .146.

I then reconnected the third STB and was getting three errors. This adds
..188 to my list of error IPs.

So it appears that the STBs are causing the errors.

I have alreading included the STBs in my MAC filter, and I have also
assigned all 3 STBs their own IP address in my DHCP Reservation List.

Any further suggestions?

Don
