Setting VLAN for iSCSI Specific Traffic - Error Encountered

[theprez1980]

Hey All -

Brand new to Proxmox but am familiar with eSXI and perhaps that's what's confusing me. Here's a quick overview of the network:

2 Network Cards - 4 ports.

One card is specific to Proxmox and VMs with eno1 and eno2, both configured as a LACP bond with the 192.168.0.0/24 network and a 192.168.0.254 gateway specified in the vmbr0 bridge. All is working here fine and I've confirmed on the physical switch the bond is established.

The other card is also configured as a bond with enp5s0f0 and enp5s0f1 and instead of a second bridge, I used a "linux VLAN" - bond1.100, I've specified the LAN, 10.0.0.2/24 and 10.0.0.254 for the gateway and it will not save this configuration. It will tell me "gateway: Default gateway already exists on interface 'vmbr0'"

Why am I not permitted to specify a different gateway? If I remove the gateway entry, it will save... and it appears to work but am unsure. I do know the bond is up - I can see it in the switch also.

here's a pic in case it helps of my network config.

Thanks

Hi,

There can ever be only one gateway, per definition.
By setting 10.0.0.2/24 as CIDR, a route is automatically created for the 10.0.0.0/24 network via that interface.

Depending on what you want to do, you may need to specify routes for the second network.

Two helpful command are ip a and ip r, which will show the current network interface configuration and the configured routes, respectively.
