I am studying the possibility to create a 2 wan failover system.
WAN1 = LTE 4G
WAN2 = Virging Broadand.
WAN1 is set a passtrough with public IP
WAN2 is public lan 192.168.1.xx because if i set virgin router as modem only, I then loose my static IP.
I need the static IP for my server to acces my backup server at home, so once I have the 2 wan failover setup, how do I know whch IP to configure in my server to access the office backup server behing the mikrotik router?
…use dynDNS…it’s as simple as that.
Most likely your MikroTik Router has already registered a DNS with the mikrotik cloud . look under /ip/cloud in the router config…it’ll change when the main WAN interface switches over.
As Hominidae said dynamic DNS is useful for situations such as this. Providing the DNS TTL is low and will update quickly and not cause connectivity issues while waiting for the change to propagate.
You can also use several other dynamic DNS providers if you utilize scripting. If there is a Mikrotik on both sides you options increase but for single side this solutions seems like the most logical.
