We have a Mikrotik PTP link that feeds a few AP's with bandwidth from multiple ISP's. I'm in the process of configuring a PC router obviously running RouterOS (v. 2.9. so that the remote end of the PTP link is connected to the WAN interface of the router and LAN interface connected to a switch along with the AP's.
My question is, is it possible to put IP's from the two different ISP's on the same WAN interface and use policy based routing to send the incoming traffic to the correct gateway for Internet access? I know how to mark the packets based on Src IP address but I'm not certain how to properly configure the static routes.
When I do configure the static routes for the different ISP's however, RouterOS seems to only want to bind to one or the other of the IP addresses on the WAN interface but NOT both. Is this possible to route traffic down the PTP for both ISP's coming from the same WAN interface?
