I have a WSUS server on a machine with 4 NIC ports. I have added a permanent route which "most of the time" forces the WSUS to use the desired NIC to get updates from Microsoft. (route -p add 0.0.0.0 mask 0.0.0.0 192.168.50.1 metric 1)
But when the server reboots it automatically recreates a route to the NIC card where the clients connect. (192.168.1.1) The result it most of the time after a reboot it will start using the other NIC to download updates, which rapidly consumes the cellular monthly bandwidth. (The cellular NIC is faster.) I have tried several things, including firewall settings in the Pepwave Surf SOHO router.)
How can I prevent the creation of the alternate 0.0.0.0 route or force the machine to ONLY use the desired port for internet access?
