I'd like to set up WAX IP(like 192.168.11.x) as different from Router(192.168.1.x) and share data from all devices connected with router.
There is a NAT mode option allowing to have a single, local SSID NATed many2one onto a single LAN IP address, see the NAT Mode shown in the fine Insight Managed WiFi 6 AX6000 Tri-band Multi-Gig Access Point Model WAX630 User Manual on p.205 ff. Keep in mind these makes up a fully isolated IP subnet, intended to provide basic Internet access to the SSID, but no further communication or subnet access. Useful for some kind of Guest or BYOD deployments only..
