I have a captive portal splash page I need to be presented to only 1 Open Wireless SSID on a WatchGuard AP controlled via the XTM330. The WatchGuard is not able to present the required splash page however I do have a secondary router that can, the splash page authenticates internet access. There is only 1 internet connection.
My thinking is to connect my secondary router into the internet connection alongside the WatchGuard. Then on the WatchGuard connect the SSID's related VLAN to an Optional interface connecting to my secondary router with DHCP relay enabled.
Would this work with wireless clients getting the splash page?
