The only thing that's really going to happen is that you might create a
double FW situation where packets/traffic that should come through the FW if
either one is being used individually is being blocked, because both are
being used.

I do use two packet filters, when my laptop has a direct connection to the
Internet. Vista FW or some 3rd party personal firewall are not firewalls.
They are packet filters. I use Vista's packet filter, and I also use IPSec
another packet filter that's on Vista to supplement Vista's FW/packet
filter.

I hue the AnalogX IPsec rules, which I have made my adjustments to the
policies
