Using STATIC WAN IP but not wasting on 1 Host.

[fbeye]

Hello!

I am new to Proxmox and am loving it immensely. My HPE Proliant Gen10 has 4 NIC's. eno1 has a bridge to vmbr1 and every CT or VM I use and choose vmbr1 grabs whatever DHCP IP it can from the network eno1 is connected to. I am good for that, as everything can use the default Cisco FPR WAN IP.
But I want to utilize a 2nd WAN Static IP but not waste it on a host.
The eno/vmbr is on the 192.168.5.0 network which reaches to x.x.x.182 WAN IP. BUT I have 192.168.5.66 NAT'd to x.x.x.177 WAN IP.
How do I make eno2 to be 192.168.5.66 (which uses x.x.x.177) and then create a vmbr2 but have that have a subnet of 192.168.6.0 and whatever CT.VM I use and want to use vmbr2 they can all share the x.x.x.177 WAN IP?
I suppose I could, on my Cisco SWITCH create a vlan2 and do it that way but I wanna reduce my hardware.
I hope this makes sense; I wanna use a 2nd WAN IP for proxmox hosts but not waste it just being abe to use it on one, so I wanna create a subnet ON that 192.168.5.66/vmbr2/eno2

Hmmm, would I just make a Linux vlan using eno2?
I assume that would create a new subnet under the eno2 (192.168.5.66 and x.x.x.177 WAN) and then have whatever vlan subnet I want all leading back to the one WAN ip, as to not waste?

Would I give eno1 an IP address or create a Linux Bridge vmbrx and give that an IP address. And then, would I do a Linux VLAN on the vmbrx?

I found this; It seems to be exactly what I was seeking.
