Congats to all parties involved for doing the right thing here. A reminder that NZNOG is not the place to post issues like this unless you have talked to the network operator in question first (which was done in this case). It would smooth things over if people in future would put a small note like "X has been advised" in the post so that people know. Also a Congrats to Walker Wireless for coming out so fast with a reply. Good to see that the old days of witch hunting on the list are over.

We have noticed this and have taken action to stop these SNMP polls from reaching other ISPs. The polling of addresses blocks managed by other ISPs was purely accidental and should not happen again.
Walker Wireless is more than willing to investigate incidents like this directly. If anyone has concerns about unusual activity orginating from anywhere in the Walker Wireless network please contact our Network Operations Centre on 0800-WWCARE or myself directly.

Hi all,
Has anyone else been seeing mail1.walkerwireless.com attempting to break in to their border routers? Picked this up on a routine log audit.
Although we actively block and log this sort of activity, others may not be aware of it.
Of particular concern is the attempted use of the ILMI exploit, detailed at http://www.kb.cert.org/vuls/id/976280 which has no legitimate reason to be seen.
Attacking machine is running Checkpoint FW-1 mail server!
Cheers,
Gordon Smith CCNA Network Operations Manager
