Im running out of ideas what the hell it is.  I reinstalled XP, exact same problem although not as many entries added (b4 reinstall had 9 pages full of bogus NAT entries)

Thats whats in there currently, the one im most concerned with is the one using ICMP.  I am not running any p2p programs (clean install with just basics installed -  Zonealarm, AVG. all latest XP updates applied)
