Multiple gateways on a windows server
Posted on 2011-05-10
I have two windows servers which needs to communicate with each other as well as with a set of desktops. They are in cluster with a heart beat connection between them thru a layer 2 switch.
Each server has 4 NICs. 2 NICs are teamed and set with a defult gateway of 172.30.0.1. 3rd NIC is setup with 172.31.0.1 as default gateway and this subnet is purely used for a cluster heartbeat connectvity purposes.
When the sever has to send the packets to the desktops (192.168.x.x) via the 172.30.0.1 gateway, sometimes it randomly sends via heartbeat network (172.31.0.1 gateway)and the packets are being dropped at the first hop itself.
I have manually setup route entries in the server to use the 172.30.0.1 gateway.. but still the problem persists. Is there anything i could do here?
