Do all subnets need their own separate default gateway
" the gateway needs to be on the network, right? Yes. But that doesn't mean each (sub)network needs its own physical interface . Routers are usually able to understand Virtual LANs ( VLAN ), which means a single physical interface (plug) can have multiple virtual logical/ VLAN interfaces associated with it.

Single Vlan interface as gateway for multiple subnets
I've since stopped but encourage others to set up, coordinate, and facilitate study groups. I've made the community public so now anyone should be able to post. Good luck and have fun!! MembersOnline • networkbridge2 Single Vlan interface as gateway for multiple subnets
If I understand what you are asking this sounds like a secondary IP address (es). interface vlan 10 ip address 10.10.10.1 255.255.255. secondary ip address 192.168.1.1 255.255.255. This is not best design but it is sometimes a necessary evil. This will allow multiple subnets on a vlan .
Single VLAN with multiple subnets
Some coworkers of mine and I are having a debate. Here's the scenario: A single-VLAN (all VLAN 1) network has multiple /24 subnets . Users are on one subnet , some servers are on Subnet 2 and other servers are on Subnet 3. There is a Layer 3 switch acting as the default gateway for all Subnets . In this specific scenario, it's an HP switch. The HP switch is uplinked to a Cisco switch which is, in ...
In a DHCP running environment, adding multiple subnets to a single Vlan is not feasible All the network and security devices won't support adding more than one subnet to an interface .
Single VLAN can support multiple subnets

To configure a single VLAN across multiple subnets , you must add a VIP for the VLAN and configure the routing appropriately. The following figure shows a single VLAN configured across multiple subnets .
Vlan routing with multiple gateways.
If it does, you could configure VLANs 10, 20 and 30 on that switch and have it route the different subnets . With a policy route on Switch B, you could have it setup so that devices in VLAN 10 are directed to pfSense for Internet access and devices in VLANs 20 and 30 are directed to Zentyal for Internet access.
Scope Deployment example: Solution Without the VLAN interface configured on the FortiGate and with L2 switches the solution would be to configure all subnets on the FortiGate interface with one primary subnet and the reset as secondaries and create a firewall policy where: Incoming and outgoing interfaces are the same interface .
