Gus,
Looks like your .2 machine is trying to connect to your .1 machine from a variety of different ports to some kind of web interface; maybe for a sql database of some sort? I am not totally sure
I would not be too alarmed - looks like it's just restricted to your internal ip's - I did not see anything shooting out; all that action (it's like a packetstorm) will degrade the performance of your nic so the dl/upl speeds will suffer.
Take a look at what's running on the .2 box, that may provide some more clues
Hope this helps some and someone please correct me if I am wrong
/me promises to stop by #holics more often
