Invalid destination address on my firewall logs

kierankelly 20 years ago

Im using a netgear wireless firewall modem router DG832GT and have Netgear access points WG602v3. My LAN IP addresses are on the

192.168.254.--- range. I'm blocking ports 6346 - 6348 (gnutella et. al.) in the firewall rules. My access points keep crashing and the logs from DG832GT are indicating a lot of trafic being blocked with a address of 1.0.0.0 Here is a sample from the logs: Fri, 2005-10-28 23:09:14 - UDP Packet - Source:64.233.240.146,6346 Destination:1.0.0.0,6346 - [gnutella match]

This address is not a valid addres on my network so where is it coming from? Or how do I trace it and block it?

TIA Kieran

That's the good news

Obviously, there is a configuration problem with your access point, and perhaps with the firewall as well.

OK - you are posting from a DSL link in the UK. 64.233.240.146 is some host apparently in Troy, Michigan, USA (about 25 KM North of Detroit, or 400 KM East of Chicago). Now, if that packet actually originated in the USA, any of the backbone routers between the source and Europe would have dropped it as unroutable. As you note, 1.0.0.0 doesn't exist, so you can't get there from here.

My guess is that your router is misconfigured and is port-forwarding this packet under the impression that 1.0.0.0 is another local address (you have a typo in one configuration).

Maybe, you should be asking this in alt.internet.wireless.
