VMX Block Countries

Have a customer that has several on prem MXs at multiple locations. They also have a VMX100 deployed in Azure. Layer 7 rules for countries is not available on the VMX but it is on the hardware MXs. 

 

Question: What would be the best practice for blocking a particular country from the VMX ?

The VMX is only used for terminating VPNs and nothing else.  People don't usually implement country blocking for VPNs.

 

I am not very confident that country blocking applies to MX on-premise either.

I have both vMX and On-premise MXs, and I can't find L7 rules for countries neither of them. Could you show about that more particular?

For on-premises MX,

  1. Go to Security Appliance -> Firewall
  2. Scroll to L7 rules. 
  3. Click add rule
  4. Scroll to bottom of drop down box to find countries
  5. You can also update this using the MX l7 Firewall calls in the Dashboard API.

As @Netwow states, you do have to have an adv security license. (But my company ONLY sells MX with adv security.)

 

I'm broadly speaking not a fan of country-based blocking, even though we do it at a few financial customers because it makes their auditors happy. I don't think it's effective in a day and age where anyone can buy a prepaid credit card and spin something up at a cloud provider.

 

I do think it's effective at accidentally breaking things, especially in the case of some of Microsoft's IP space. Or just preventing access to useful things and increasing the risk of shadow IT.

Go to SD WAN>Firewall>Layer 7 > scroll to the very bottom and you should countries. I believe this requires an advanced security license .
