failed shields up test



Hi,

I installed 10.3 on both my computers now and I tested their security today
on grc.com. All ports were closed according to the test, but a ping was
returned.

I looked into th efirewall settings, but found no allowed services in DMZ,
internal - and external zone. I use a Fritz!box modem that has it's own
firewall.

What can I do to solve this?

TIA, Derk
