Second LAN on the WAN1 port - Flint2

Technical Support for Routers
1

I’ve an ONT device on WAN port and I need to connect by Telnet to its IP address (192.168.2.1).
I 've a PPPoE protocol on WAN1 .
My local DHCP ln is 192.168.1.1
I think I need to create a second lan on the wan port and route the the telnet access from a local network IP (computer 192.168.1.x) to 192.168.2.1 .

Please could you help me to do that ?

thanks

Does your ONT have multiple ports or just the one that is connected to your Flint 2?

Second router use lan1 port and will auto dhcp from first router.

I think you can try an alias on this interface (static IP). Additional a static route to the ONT IP via the alias interface i guess.

It should be configurable via Luci.

I did the same with my RPi4 so that i was able to use the single LAN Port also as a WAN port.

I’ve simply made a new interface on Eth01 with static address 192.168.2.2 and firewall rule enabled
