Thanks@karstenl and @cmr , that's very bad of meraki's HA solutions. I setup HA just in case of old MX250 broken. I don't want to introduce another router for NAT (between MX and ISP)to make network more complex, our MX250 act as NAT gateway already， double NAT is really bad. If connect the same cable together, put the new MX250 into disable state, once the old MX250 broken and we received the alert email, we enabled the new MX250 from the dashboard, and disabled the old MX250. Is this kind of solutions OK? we can accept one or two hours network interrupt in our office.

hello, I have an old MX250 for several years. now I purchased another MX250 for reduntancy only in case of this MX250 HW failure. I have two ISP dedicated internet connection, and I am using two lines at the same time with load balance policy. and each ISP just give me one public IP address only. so Maybe I just connect ISP's incoming cable connection to one of my switch, and then connect my WAN port to the switch，and Can the MX250 auto switch to use the only one public IP address automatically ? If WAN1 or WAN2 failed, still use the old MX. if OLD MX failed, then dashboard can switch to the new MX, WAN1 and WAN2 in the new MX will re-use those ISP public address. Can this kind of design work ? Thanks
