A duplicate entry already exists VIP

Taha1 · ‎11-28-2022

Hello EvryOne

We are using FortiGate201F v6.4.11

We have an internal web based application and I want my users to be able to connect to that application from outside our network.

So I wanted to NAT between our public IP and private IP

So am getting the below error:

A duplicate entry already exists.

The extip is overlapped with the gateway of static route.

So I searched the firewall I found that the same Public IP is defined as Gateway Address .

am not sure what that’s mean ?

Would any one kindly help.

Thanks.

Best Regards

That generally means the static route was misconfigured whoever configured it. You need to judge if you can/should remove it based on the destination subnet.

As I said two years ago, if you "found that the same Public IP is defined as Gateway Address", "That generally means the static route was misconfigured whoever configured it. You need to judge if you can/should remove it based on the destination subnet."
