finding ip that can be accessed from outside

Hello Experts,

I have access to the corporate firewall which is fortiGate 110 I am looking at the range of public IP address that I can use. I never used this firewall and I want to know how to find this information.

Thanks,
LVL 4

Smartmanwin,

I'm not sure I really understand what you'd like to accomplish? Do you want to know what your IP block is or you'd like to know what the IP of the FW is? If what you need is an IP address for your FW then you contact your ISP, you can get one static IP or ask them to assign a block of IPs.

The only 100% accurate method is to check with your ISP who will advise what public IPs they have assigned to you.
You may be able to take an educated guesss by checking the link from David above, and reviewing any existing NAT or interface configurations.

Not familiar with the location of settings but looks like Firewall Objects > Virtual IP > IP Pool might have some related info

I know from the firewall we can find out what IPs are accessible via the internet. I am new to this environment and to the firewall and it will help to find out. The ISP will be my last resort but it is taking time because I still need to be in the contact list.

Camy, I will check the virtual IP pool to find out.
