IP Spoofing??

[rought]

I was checking my log files.. (router)
Came across an “IP SPOOFING”
Anyone have an Idea what this means..
See pic.. Note: I can change my ip so not going to bother and black out the numbers,

google it?
i found several links that really only partially explain it:
http://www.windowsitpro.com/Article/ArticleID/9253/9253.html -trojan ip spoofer
http://www.effectivepctools.com/index.php?scr=googleus&ag=ip_spoofing&ad=475 - ip spoofing (hiding) progs
http://searchsecurity.techtarget.com/ateQuestionNResponse/0,289625,sid14_cid487139_tax285453,00.html -some security stuff about ip spoofing and hijacking

http://www.google.co.uk/search?hl=en&q=define%3A+ip+spoofing&btnG=Search&meta= - some google definitions (sounds dodgy, illegal access to your comp)

it seems to be a method to stop people seeing your ip so i imagine you must have done something but 1 of the links is about an Ip spoofer trojan

i would try encrypting your network, 1 site i found said something about that

Thanks Conker for your time..I appreciate it….
Nice links but kind of the same thing I found… that it could mean anything.
I ran a 1 hours virus scan..( I’m running 8 Western Digital 74 gig Raptors and a 200 gig USB) so takes a while.. everything came up clean. But there are 4 computers on my router..
Personally I think someone is after my 100 gigs of porn…lol..
Thanks again .. if anyone needs a stand alone anti virus scanner that needs no installation try this one..
