This article how to troubleshoot the error 'Can not set port ranges over 16' when editing mappedport on Access proxy setting.
Scope
FortiGate.
Solution
When trying to edit the mappedport on the current setting of access proxy with mappedport will encounter:
config firewall access-proxy
edit "Server"
config api-gateway
edit 1
config realservers
edit 1
set mappedport 1 2 3 4 5 6 7 8 9 10 11 12 13
end
Can not set port ranges over 16 Command fail. Return code -1
Even if the number of mappedport is under 16, the error 'Can not set port ranges over 16' can still be seen. The system only accepts 8 mappedport ranges when using CLI.
The issue is aware of, and the current workaround is:
Making the change on the GUI instead of the CLI.
Delete the object and create a new one with a new mappedport.
