Allow Fossil:

netsh advfirewall firewall add rule name="Fossil" dir=in action=allow program="C:\bin\fossil.exe" enable=yes
netsh advfirewall firewall add rule name="Fossil" dir=out action=allow program="C:\bin\fossil.exe" enable=yes

as it turns out Fossil doesn't need this. However the command works so saving for posterity.
