Do you already have a 802.1Q trunk between your 2960 switch and your ESXi host? If not, see if you can do that. This way you can put the ZS router on VLAN 1 and VLAN 10, and have it be the gateway for hosts in VLAN 10.
I have plenty of experience with that sort of networking. The ESXi host can have several virtual switches; one for each VLAN.
(I’ll elaborate on this post later on.)
