I don't know if the IP Ranges on the Internet are that specific, but
if they are you would just create the right type of Network object
in the Toolbox (probably a series of Address Ranges Objects). Then
create a Deny Rule that uses those Objects as the Destination. If it
is a Publishing Rule then these would go in the Exceptions List of
the "From:" part of the rule.

I do not know of any list of IP Ranges associated with particular
countries. There may not even be such a thing. It may not even be
possible,...such an "association" may not even exist. Maybe someone
else will have ideas on that.

Phillip,

Thanks for your answer and also all others. Yes, when nothing is
configured all inbound is blocked. I understand that. Fact is that my
server does not make much sense if I keep it that way :-)

I have several services running and published. What I have done is that I
create a Deny Rule that sits above all other rules:

- Name Block All
- Action Deny
- All Outbound traffic
- From 'Block list'
- To 'All Networks and local host'

This blocks all traffic from and to all IP addresses and networks listed
in the 'Block List'. I tested this and that works just fine. I want to
import a range of IP networks into that list to block a certain country, I
just hate Monaco :-)

Oh well, I will look into the suggestions others made and try to fix
something in VB that imports those lists. I am only wondering how this
will effect performance in ISA...
