We have a single public IP connected to the WAN interface of a Fortigate 60 running OS 3.0. We have successfully mapped multiple select ports to any single server within the office using a Virtual IP static map definition combined with a policy to route the selected ports.
The problem is that we would like to map another different set of ports to a second server (ex: Server1 hosts email while Server2 is a Terminal Server). In creating a second Virtual IP definition we receive the error "A duplicate entry already exists".
Please help, how do you host multiple internal server of different types behind a single public IP?
