Second Proxmox Access IP

Hi,

Recently purchased a bare metal host that has the one network interface eno0. On deployment this interface was bound to vmbr0 so that it can be access directly via the internet.

Since then a firewall has been installed where a second internet address is acting as the WAN interface on same Vmbr0, and Vmbr1 as the internal LAN and default gateway with 10.10.0.1.

There are various servers in the network, each use 10.10.0.1 (firewall LAN) as the default gateway, but all the the same subnet of 10.10.0.x/24

Vmbr1 has been configured with 10.10.0.99 but I can not add a default gateway due to the following error:

gateway: Default gateway already exists on interface 'vmbr0'.

This is because only one gateway can exist at at time, and this is already on vmbr0

What I essentially want to do is be able to access / manage Proxmox via the internal IP address 10.10.0.99 and disable the public one (unless I need to enable it in the future).

I can ping 10.10.0.99 if in the same network, but because I can't give it a gateway (10.10.0.1 to firewall) its not reachable by any other subnet (other subnets exist via a VPN site to site on the firewall)

I understand the logic might not make sense here, and probably need straightening out. In essence I would like the 10.10.0.99 reachable by the wider network before adding / deleting / amending the current direct external access.

One thing I could do is access Proxmox via an internal server that is in the 10.10.0.x/24 range, remove the current default gateway, and add the new to Vmbr1. Before I do, wanted to get some advise

Thanks in advance for any advise.
