RB750 dual use local router with nat and hotspot

Hi to everybody, I had try for long time to use this board like lan router with nat and firewall for office pc on the first 3 lan interface, and the last 2 lan configured for hotspot with remote radius server.
when I configure hotspot, I lost my lan connection.
I assign to lan1 the addres of the network where I had radius server, 10.1.1.0/24
I create a bridge with lan2 and lan3, this bridge has address 192.168.1.0/24
I create a nat roule for masquerade.
I define a DHCP server for the bridge.
It works, I had 2 lan and 1 wan, no authentication required, I can use all the band I had.

Is possible use lan4 and lan5 for hotspot access, using “hotspot setup” and enable the authentication for hotspot user on the radius that is on the subnet 10.1.1.0/24?

Thanks in advance.

a) when you bridge lan1, lan2 and lan3 the router IP within 10.1.1.0/24 should go on the bridge interface, not the lan1 interface. You do not need an IP within 192.168.1.0/24 on the bridge at all.
b) bridge lan4 and lan5, and run the Hotspot wizard on that bridge interface. You can then use a RADIUS server within 10.1.1.0/24 for authentication.

Thank you, I do not bridge lan1, lan2 and lan3, only lan2 and lan3 because I use theese two lan, 1 for office and one for my lab. this is the only reason. I will try bridge lan4 and 5 then hhotspot setup. I will let you know later.

I am using RB750 and want to use it’s
ether1 for WAN,
ether2 and ether3 for LAN
and ether4 and ether5 in bridge which will manage bandwidth only

ether3 and ether5 will connected in the same switch.
Is it possible ?
