I would like to setup Asus RT-N16 with TomatoUSB to serve as an access point for two Wireless SSIDs.
Router is on a local network. Router must not be a gateway for wireless, but a bridge to local network. Router must have it's IP for example 10.10.0.1/16 and gateway is 10.10.0.254/16, DNS is 10.10.0.250/16.
First SSID must have have authorisation and get an IP from DHCP on the LAN, not from this router, this IP must be for example 10.10.1.100/16 to 10.10.1.150/16, gw 10.10.0.254/16, dns 10.10.0.250/16. This I can accomplish.
Second SSID must be without password (open) and be in same local network but have different network mask: 10.11.0.0/16. So clients must get IPs 10.11.0.100/16 to 10.11.0.150/16, gw 10.11.0.254/16 (which is the same gateway as 10.10.0.254), dns is 10.10.0.250/16, or 10.11.0.250/16, or routers IP if it will have additional ip of 10.11.0.1/16.
How can be this accomplished? I tried different combinations and both SSIDs get ips from 10.10.1.100+. Also WAN port must be bridged with all 4 LAN ports. If connecting to any LAN port off router, client must get IP from DHCP not on this router and from 10.10.1.100+.
