Re: [cobalt-security] Qube2 Firewall "feature"



I have been trying to use the Cobalt Firewall wizard to generate my ip
filters. The ones it suggests do not make a whole lot of sense to me (may be
my newness at figuring out the Qube2 ip filter logic). I thought I read a
post from someone saying that the wizard and/or the Qube2 IP filtering method
had a flaw and that Cobalt was working on it. However, I have not been able
to find the message nor anything in the KB that helps.

Do you know if the wizard and/or the Qube2 ip filters have any bugs? If so,
what?

Basically, I want to set up filtering to accomplish what you have indicated
in your message. Any tips on setting up efficient filters?

Does the Qube2 log filters that are rejected? If so, where and how to I
review them? I'd like to know if an attempt was made to get through the
firewall.

Thanks.
