You're seeing IGMP packets; some ISP's send these -- I see them from
Earthlink, for example.  I haven't discovered their use in any tcp/ip
textbooks.  You can tell your script not to log these entries, or just
accept IGMP.  If your pppd is on a timer (demand mode, or through diald),
the packets may keep your connection up when you don't want it, and,
unfortunately, those timers get hit before iptables can block them.  If
you're using diald, set the "everything else" timeout to less than the
interval on these packets.  Good luck.
