IKE service
Freshman Member
Hi,
Our analysis shows that the IKE service ( gateway) is clearly visible and can be used by attackers for reconnaissance and targeting. How can we make the IKE service not clearly visible ("hide") in ATP 200?
I am waiting your answer

To hide the IKE service on an ATP 200, you can configure the firewall to block or obscure IKE traffic by disabling unnecessary services or changing the default ports for IKE (UDP 500/4500).

How would you change them default ports for IKE (UDP 500/4500)😏

I suggest you limit the incoming traffic to IKE service with GeoIP restrictions via Security Policy rules. It works perfectly for us.
