Troubleshooting Tip: How to fix error 'Conflicts with virtual server source pool address' when adding Link Load Balance's Gateway IP

[Khidzir_MN]

Description	This article describes how to fix the error 'Conflicts with virtual server source pool address' when adding the Link Load Balance's Gateway IP.
Scope	FortiADC, FortiADC-VM.
Solution	FortiADC will prompt an error if the Gateway IP is the same as one of the Server Load Balance's NAT Source Pool IP. Go under Server Load Balance -> Virtual Server -> NAT Source Pool: This is currently the expected behavior. Using the gateway IP as the source NAT IP at FortiADC may break the return connection, as the traffic may stop at the gateway device, since the IP used as the SNAT is located at the gateway device, and the traffic may not reach FortiADC as the originating device. If the Link Load Balance's Gateway IP is required to use the same IP as the NAT Source Pool IP for the Virtual Server, use a different IP for the NAT Source Pool IP to avoid the error.
