firewall question

hello there, I just installed the Sygate Personal firewall on my pc and its doing a good job stopping popups and the rest but everytime it starts up i get messages like
'IPv6 (tcpip6.sys) is trying to send a packet. Do you want to allow this protocol driver to acces the network?'
and
'NDIS User mode I/O Driver (ndisuio.sys) has recieved a Broadast packet from the remote machine [10.115.64.1]. Do you want to allow the program to access the network'

and similar things for ' Generic host processes for Win32 services' and NT Kernel and System'

Should I be clicking on the YES or the NO for these?

thx
