Is it possible to config failover with only one int(WAN)?

Hi every1,

I am running hotspot in x86 based PC with just 2 network cards, LAN & WAN each. I have two public ips, one in Radio and other in Fiber.

Is it possible to configure single WAN interface with two ips(Radio+Fiber) to do the failover.

Rgds,

Good to know that but how exactly, Is it multi homing?

This can be done in variety of ways.
For example one way could be that you insert both WAN links in single switch, and then connect this Switch with mikrotik WAN. In Mikrotik , you can add secondary IP address on the WAN interface, means WAN interface will have ip addresses for both wan links. now create secondary route for your second link. Then simply apply fail over scenarios as per your need, for example either via scripting, or using virtual hops, or using netwatch to initiate scripts if any links goes which can also email you the info too , I wrote some rough notes about fail over on my blog too.

Agreed. That is how I would do it as well.

Thanks to you both. I did just like aacable has written and with simple ping timeout method.
