 Are you running a firewall with iptables connection tracking?  Are the
extra connections (that don't show up in netstat) from internal addresses to
external addresses?  (i.e. neither end of the connection is your firewall's
IP addr?)

 If so, then that's normal.  netstat only shows connections from the local
machine.  iptstate reports the state of the netfilter connection tracking
