Modifying text in portal messages
Generally, you can change any text that is not part of the HTML code nor a special tag enclosed in double percent (%) characters. You should not remove any tags because they may carry information that the FortiGate unit needs. See the preceding section for any exceptions to this rule for particular pages.
To modify portal page text
1. Go to System > Network > Interfaces and edit the interface.
The SSID Security Mode must be Captive Portal.
2. Select the portal message to edit.
• In SSL VPN or WiFi interfaces, in Customize Portal Messages click the link to the portal messages that you want to edit.
• In other interfaces, make sure that Customize Portal Messages is selected, select the adjacent Edit icon, then select the message that you want to edit.
3. Edit the HTML message text, then select Save.
4. Select OK.
