Solution |
To change the WAN IP to a new IP address make sure to do changes as below:
Go to Network -> Interface -> WAN interface and provide a new IP address.
Under Network -> Static routes, provide a new gateway IP address on the static route.
Also, if SSL VPN is used, make sure the FortiClient -> remote access -> remote gateway field has been changed with the new WAN IP address.
If site-to-site VPN is configured, make sure to change the remote IP address of the remote side of the tunnel to the new WAN IP.
Perform this process during a maintenance window to avoid impairing traffic.
Contact TAC for additional support if issues still occur following the WAN IP change. |
