André, thank you, I wasn't even aware that ALB existed on my NAS.
Question: So would the attached topology work then, using two separate switches, one for each of the NAS connections? If so, I think I would like to use ALB on the NAS instead of NFS multipathing from the ESXi host.
I would assume vmnic1 and vmnic2 would remain setup with the default "Route based on originating virtual port" but I'll have to do more research on this.
Thanks!
