Good Evening,

Is this a correct network configuration? All of the routing takes place on my switches and firewall. Each server is able to ping the other on each subnet. Is there an issue with using multiple gateways on the same NIC? New to networking. Thank you!

What's the best way to handle multiple gateways?

Here is my etc/network/interfaces

auto lo

iface lo inet loopback



iface eno1 inet manual



auto vmbr0

iface vmbr0 inet static

        address 192.168.48.10

        netmask 255.255.255.0

        gateway 192.168.48.1

        bridge_ports eno1

        bridge_stp off

        bridge_fd 0



iface enp8s0f0 inet manual



iface enp8s0f1 inet manual



auto eno2

iface eno2 inet static

        address 192.168.49.10

        netmask 255.255.255.0

        gateway 192.168.49.1



auto enp10s0f0

iface enp10s0f0 inet static

        address 192.168.50.10

        netmask 255.255.255.0

        gateway 192.168.50.1



auto enp10s0f1

iface enp10s0f1 inet static

        address 192.168.51.10

        netmask 255.255.255.0

        gateway 192.168.51.1

That configuration above is giving me an error message on boot. The servers are able to ping each other and connect through each separate IP. There are 3 NICs on the servers.

I have hardware switches and a firewall taking care of the VLAN between the 3 servers.

Would configuring linux VLAN within my network configuration file solve the failed start?

I added the tags to my configuration file, but I'm unfamiliar with how to do it or if it will solve my problem. I'm also unfamiliar with post-up and policy routing.

This link will describe how to do "load balancing" beetween this two gateways...

It is important for you to read it carefully specially on the start, as the author explain what will gonna be each variable in the configuration.
