Inbound and outbound security rules

tinhnho — Mon, 16 Sep 2024 18:23:02 GMT

Hi Experts,

I have 2 rules which are for Inbound/Outbound traffic and both are using Geo locations. These 2 rules have the Negate feature checked.

Inbound and outbound rules allow 20 countries, and the rest are denied (China is on the denied list).

My question: There are three websites that are hosted by China's public IP addresses, and my company needs access to these sites. I definitely don't want China IP addresses visit our own websites. What are the best ways to allow access from my company to these China's websites? Do you need to add China to the allowed list in our outbound rule?

Hi @tinhnho

Security rules are processed top to bottom, so if you have a blanket deny/drop rule, simply adding a smaller exception above it will allow you to access these resources while still blocking everything else

So for example: above your embargo rules that block all the countries, you can add a rule that allows outbound access from your internal users to 3 fqdn objects representing the chinese websites.

all other chinese websites will still be blocked by the below rules
