Dear Christine Kronberg,

Microsoft ISA Server can't filter events from Microsoft Mouse, but
Microsoft Mouse can be bound to computer. It's security risk, but I know
how to secure mouse without ISA and I accept this risk.

IPv6 can not be filtered by ISA, but it still can be filtered by
different tools, or by it's own means, as IPv6 support network-level
security. Unlike IPv4, IPv6 supports authentication, integrity checking
and encryption natively. See ipsec6.exe and descriptions for Security
Association Batabase and Security Policy Database.
