What is this all about? I don't recall ever seeing this in the log before. If it's some kind of hacker thing how do I stop it?
Fairly new to this wireless thing - so some info would be great!
Hi anneaceae, welcome to Geeks to Go! Assuming the spoof attack was correctly identified by your D-Link (not alot to be gained by trying to get at port 110 via spoofing other than an attempt to get your email...even if sucessful, one would have to crack a username/password here to continue so it's possible that your D-Link has misidentifed the event), here is the Readers Digest condensed version: the 192.168.x.xxx address that you noticed is one of a small set of IP addys that are reserved for private internal use and as a result are not routable on the global Internet. Bottom line: you can't use one of these IP's to get anywhere on the 'net. However, if one can pretend to be one of these IP's, it's possible to gain access to an internal network. Hence the spoofing: looking like something they're not.
Most, if not all, routers/firewalls will detect this kind of behaviour since a private IP should NEVER be coming from the outside world to your network. Your D-Link is obviously capable of detecting this kind of probe, so you have nothing to worry about.
Hope this helps!
