Block Firewall Access through Public IP

[ehsan12345]

Dear Professionals

My company firewall is accessible via public IP from outside network (Untrusted Zone). I want to block access to firewall via public IP from outside network, so only user on trusted zone should have access to firewall. What shall I do? Please help.

Thank you

Hi,
by accessible via public IP, what do you mean? Is it completely open for every protocol now?

If you block everything from outside, you might block too much. If all traffic coming from outside is blocked, then you might not have any internet access at all. You can block everything except traffic originating from the inside first. So the reply traffic can come back in.
Do you want to block ping? SSH?

What type of firewall do you use?

How to you access it? SSH or https?

We access it via https

Then you should block HTTPS from the outside to the firewall. This is done differently in different firewalls. What type of firewall is in use?
