2 IP Address not working in 1 VM with 2 Network Adapters in Cloud-Init

[sahiltech]

Hi Team,

I am assigning 2 IP addresses in the VM with the help of Cloud-init and I have connected 2 Adapters as well (1 for each IP),

Even though only 1 IP is pinging, the IP that is pinging is the least one.

I have tried assigning IPs single and both the IPs work, but when I am assigning 2 IPs simultaneously it is not working

Please check the screenshot as well,

I request to please help me in this issue,

Thanks & Regards

You cannot have two default gateways at the same time.

For the VM to have multiple IPs reachable from the Internet via different links you need to setup policy routing inside the VM.

Hi Gurubert,

Thank you for your quick response,

So you mean to say that instead of clou-init if I assign the IPs of 2 different gateways that will also not work?

Yes, this has nothing to do with Proxmox or cloud-init. It's routing 101.

Ohkk Understood, Thanks Gurubert,

So if I assign the 2 IP addresses of the same gateway that will work.

Hi,

That seems not be a issue with the different gateways,

Now I have tried assigning 2 IPs with same Gateways and found no luck
