Linksys + Sygate PF

I am using a Linksys BEFSR41 switch and I have SPF installed without any
advanced rules. Using SPF alone, the traffic log showed a confusing array of
Internet 'noise' being rejected and quite a lot of undesirable polls being
permitted. However, since installing the switch, I have a very clean traffic
log. The only rejections shown in the traffic log are incoming UDP polls
from the switch - and I presume these to be pings or other undesirable
signals. On the other hand, there are also rejected incoming UDP polls from
the DNS server of my ISP. As the Linsys switch is the only device that is
supposed to talk to the DNS server, I do not see how those polls are
reaching the SPF.
Can anyone explain?
