We are in the process of setting up a mikrotik RB 915 for a client. They have two WAN gateways, one for general internet access and one for a direct link to their head-office, setup as follows:
LAN 1 - Internal LAN connected to internet gateway IP: x.x.x.x/24
LAN 1 Gateway IP : g.g.g.g/24
LAN 2 - LAN connected to direct link gateway IP: y.y.y.y/24
There is a second device (a network print server) that also needs a connection to the LAN 2 gateway.
What I was thinking of for a setup was to bridge ether1 and ether2 for LAN 2 with ether1 connected to the gateway and ether2 connected to the print server. Then bridge ether4, 5 and the wlan for LAN 1. Ether3 would be connected to the LAN 1 gateway. When a pc on LAN 1 tries to establish a RDP connection to server z.z.z.z, then it needs to be routed to the LAN 2 gateway, all other traffic needs to be routed LAN 1 gateway.
I was thinking of setting the gateway for the default route as g.g.g.g/24 and then create a second route with the destination address as z.z.z.z/24 and gateway as y.y.y.y/24.
Would that setup work or do I need to do something else, maybe policy based routing? Any help would be appreciated.
