My experience with Mikrotik is zero. We need to remove our current default gateway IP and replace it with a new one. The new block of public IPs has been assigned and provisioned by our ISP. I can ping the gateway from the router. I even have one of the new IPs set up and working with a NAT to an internal server.
I have added the new IPs and and assigned them to the interface pointed at the ISP but the new IPs do not show up as connected routes in the route table.
When I add a default route using the new gateway it shows as unreachable.
Obviously I am missing something. What do I need to do so I can get the new default gateway reachable before I delete the current gateway?
I also have a second interface also going to the same ISP with a different IP. This interface and gateway is used for VOIP only. I will be leaving this interface and IP as is.
