Description The article describes how to resolve the issue when the VNC protocol does not show under New Bookmark when the user connects via SSL VPN Web mode.
Scope FortiGate.
Solution

There are cases when one or a few protocols are pre-defined to be used under New Bookmark when the user connects to the SSL-VPN Web mode, as seen below:

As noticed, the VNC protocol is not part of the protocols available. The configuration for this portal (full-access in our case) on FortiGate is as follows:

 

FortiGate # config vpn ssl web portal

FortiGate (portal) # show
config vpn ssl web portal
       edit "full-access"
            set tunnel-mode enable
            set ipv6-tunnel-mode enable
            set web-mode enable
            set ip-pools "SSLVPN_TUNNEL_ADDR1"
            set ipv6-pools "SSLVPN_TUNNEL_IPv6_ADDR1"
        next

end

 

Note:

If an option is not available under the CLI configuration for different settings, always check with 'show full-configuration'.

 

In this case, as seen, the protocol options are not part of the configuration, after executing 'show full':

 

FortiGate (full-access) # show full-configuration
config vpn ssl web portal
       edit "full-access"
            set tunnel-mode enable
            set ipv6-tunnel-mode enable
            set web-mode enable
            set allow-user-access web ftp smb sftp telnet ssh rdp ping
            set limit-user-logins disable

            ......

       next

end

 

Here, only the following protocols are allowed for the user to access: web ftp smb sftp telnet ssh rdp ping

 

To resolve the issue, the VNC protocol should be included in the configuration:

 

FortiGate # config vpn ssl web portal

FortiGate (portal) # edit full-access

FortiGate (full-access) # set allow-user-access web ftp smb sftp telnet ssh rdp ping vnc

FortiGate (full-access) # end

 

The configuration now will look as follows:

 

FortiGate (full-access) # show full-configuration
config vpn ssl web portal
      edit "full-access"
           set tunnel-mode enable
           set ipv6-tunnel-mode enable
           set web-mode enable
           set allow-user-access web ftp smb sftp telnet ssh vnc rdp ping
           set limit-user-logins disable

           ........

      next

end

 

After logging out and logging in on the Web portal and selecting New Bookmark, the option will now be available for selection:

By default, all the options are available. Depending on the network requirements, different protocols can be removed for different portals.
