LB2120 wan ip address

Hi! I'm trying to configure as failover an LB2120, but i not see a way to configure the wan ip address. I have some external services that i need to reach on the inside lan.

How i can do that?

Thanks!

    The only WAN IP the LB2120 does handle is the 4G/3G one - very uncommon that you have (and can!) configure this address fixed. Your WWAN provider might offer some "static" addresses on your SIM/contract - the IP address is done by the provider.

    Any kind of DDNS should do the job, isn't it?

     

    Not sure you got it right: This LB2120 isn't intended to bring over the broadband IP address to the mobile 4G/3G.

      The problem is the static ip address of the wan ethernet interface. In any case i've resolved in a "not so nice" way of using a router with dhcp and created a reservation before the lb2120. All work as it should but there is one more device that can be avoided.

        That's by design - the WAN Ethernet interface is just a L2 port, and has no routing functionality. It is indeed intended for connecting to an existing broadband (or whatever) router only. Only the WWAN mobile network port is routed/NATed.
