One Container, 2 Puiblic IPs with own Gateways on different Bridges

[BuLoMa]

Hi,

i got Proxmox 7.4-16 on an older Server.

2 Bridges
vmbr0 => for a single /32 IP routed over the main ip of the server
vmbr1 => an additional subnet with few ips

The container has 2 network adapters
eth0 => a subnet ip from vmbr1 with the bridge ip as gateway

as soon as i add another network adapter on bridge vmbr0 with the single routed /32 ip and the ip of vmbr0 as gateway, i can't ping the first eth anymore.

when i remove the gateway of the second eth the first eth is pingable again but i can't reach the second ip from vmbr1.

How can i add 2 different public ips with their own gateways from different bridges in one container?

Basically, a system can only have one gateway. You can't easily have two.

If you really want and need this, then take a look at this article: https://unix.stackexchange.com/a/22794

I just don't know if it works in an LXC container. In a KVM VM it definitely works.
