been moving someone into our house, and before she arrives she tells us "here's my 4 VLAN tags and their 4 corresponding /24 subnets, what's my public IP" and we log into our router pair and switch, and configure 4 VLANs, 4 CARP addresses, routing, firewalling, and NAT to one of the 6 addresses in the /29 we have from our ISP.
she moves in, lights up her switch, and everything just seamlessly works, no troubleshooting needed. dayum
