Yes, you need to have route to point to L3 switch as next hop to reach 192.168.201.0/24 &amp;&nbsp;192.168.30.0/24 networks if your Internet Gateway is router.<br />
<br />
How routers work (L3 switch do this the same way):<br />
To forward traffic<br />
1. router checks routing table to find best match (most specific route)<br />
2. - if matching route is found - forward traffic according to best match route <br />
&nbsp; (default route is the least specific route - every traffic matches at least to default route)<br />
&nbsp; &nbsp; - if matching route is not found (default route is not configured) - drop traffic<br />
<br />
If router don't have other route to destination (learned statically or dynamically) that is more specific than default route - traffic will be forwarded using default route (most likely in your case this mean that traffic would go back to internet). <br />
<br />
So, most likely, if you don't assign those route(s) traffic will be forwarded back to internet.<br />
<br />
What I would do differently<br />
- if switch support option - I would convert port to L3 port and attach Internet Gateway to that port<br />
- if L3 port is not option then I would create separate VLAN for this purpose<br />
So, there would be 3 VLANs total and internet gateway still need to have route(s) that point to L3 switch as next hop to reach Data and WiFi networks.

<div>
my internet gateway is my firewall.
</div>


<div>
If firewall has routing table, that's it, the same rules apply.
</div>


<div>
Can you give me an example:<br />
<br />
Source (ANY) Destination (Wifi(192.168.30.1/24) Service (ANY) Gateway (WiFi SVI (192.168.30.250) Interface (LAN)<br />
<br />
<br />
currently what I have?
</div>


<div>
ok I change the gateway to the 201.250 and I am still pinging vlan 4 devices from vlan 30

Good day,<br />
<br />
assistance with routing.<br />
<br />
<br />
i have a L3 Catalyst Switch acting as the core switch with 2 svi, one VLAN 4 (192.168.201.250 (Data) and VLAN 30 (192.168.30.250(WiFi). I have configured an access port on port 1 for VLAN 30 and configured a route to an internet gateway (192.168.201.2).<br />
<br />
in the internet gateway i have a route that goes back to the Catalytst Switch. <br />
<br />
Internet Gateway Route ----------- Source (ANY) Destination (Wifi(192.168.30.1/24) Service (ANY) Gateway (WiFi SVI (192.168.30.250) Interface (LAN)<br />
<br />
with the route i am able to get out to the internet fine, but, i am able to access VLAN 4 devices? once i remove the route i am unable to access the internet or the VLAN4 devices. So i think i may have the route wrong. <br />
<br />
<br />
Internet Gateway (192.168.201.2) ---------&gt;L3 Switch (192.168.201.250) -----------&gt;VLAN4 and VLAN30<br />

Switch and Routing,

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
