Multiple NFS Servers as backup destination on same LAN

[Scut]

Hi everybody,

I have my proxmox server on a dedicated server in a datacenter.
I do daily backups to a synology NAS on my local network. I did some NAT on my router for that, i use my NAS as NFS mount on the PVE.

For now, backup routine works very fine since a year or two.

I need to add a second NAS as NFS mount drive, because for some reasons i need to backup some VM on the first NAS and others VMs on the new NAS.
Problem, the NAT on the router is for the first NAS, and it seems that NFS can't use others ports on the Proxmox server ?
if i redirect ports on the new NAS to appear as a NFS sharing, the NAT would be broken for the first NAS.

The question: how make a second NFS mounting point possible on the same destination network ?

I hope the question is understanding enough (sorry for the bad english)

Thank you guys

You may be able to use DNS SRV records to achieve this, if you are able to adjust the NFS ports on your NAS and then adjust your router NAT accordingly? I recall doing this for minecraft servers once:

Hopefully this will help?
