Changing images in portal messages
You can replace the default Fortinet logo with your organization’s logo. First, import the logo file into the FortiGate unit and then modify the Login page code to reference your file.
To import a logo file
1. Go to System > Config > Replacement Messages and select Manage Images.
2. Select Create New.
3. Enter a Name for the logo and select the appropriate Content Type.
The file must not exceed 6000 bytes.
4. Select Browse, find your logo file and then select Open.
5. Select OK.
To specify the new logo in the replacement message
1. Go to System > Network > Interfaces and edit the interface.
The 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. In the HTML message text, find the %%IMAGE tag.
By default it specifies the Fortinet logo: %%IMAGE:logo_fw_auth%%
4. Change the image name to the one you provided for your logo.
The tag should now read, for example, %%IMAGE:mylogo%%
5. Select Save.
6. Select OK.
