IP range

Gel

On the Flex 200 firewall, can I increase the IP range from 254 to 512 leaving the same current network submask, in this case 255.255.255.0? Is there a possibility to increase my IPs without changing the submask?

no the submask is what limits how many IP's you have.

I guess you can have LAN1 192.168.0.1/24 and LAN2 192.168.1.1/24 and link them together by a switch not sure thats a good idea.

no, actually I have a LAN with an IP range of 192.168.10.1 with a submask of 255.255.255.0, but I need more IPs.

you need to make the submask bigger

If you need to double IP range, you can set subnet mask to 255.255.254.0

Then you can have from 192.168.10.1 to 192.168.11.254.

You will need to reconfigure all devices not managed from DHCP.
