TL-SG3210 inter-vlan communication not working

Model: TL-SG3210  
Hardware Version: V3
Firmware Version: 3.0.7 Build 20221130 Rel.42340

Hello everyone,

I am having trouble with inter-vlan communication on the TL-SG3210 switch, which I am currently using in standalone mode.

The configuration was done only in the GUI, no CLI.

I have 3 VLANS setup as follows:

1. Default VLAN, ID 1 - 192.168.10.2 - VLAN Interface
2. VLAN ID 20 - port 7(untagged) on the switch, 192.168.20.1 - VLAN Interface
3. VLAN ID 30 - port 8(untagged) on the switch, 192.168.30.1 - VLAN Interface

In the port config i setup the PVID for port 7 and port 8 as 20 and 30 respectively.

The routing table was updated automatically as such

 

Routing is enabled at the Interface level

 

DHCP is enabled on all VLANS and also Pools are created. When I physically connect a device in port 7 - it automatically is assigned an IP address from the 192.168.20.0/24 network and when I connect a device in port 8 - it gets an IP Address from the 192.168.30.0/24 as expected.

As this is a layer 3 switch what I want to achieve is to be able to communicate from VLAN 20 to VLAN 30 and also from VLAN 1 to VLAN 30 without a gateway; I was under the impression that by default inter-vlan communication is enabled and this can be restricted with the use of ACLs but I didn't manage to make the communication work and I am not sure what I am doing worng.

Any suggestion is useful.

Hi, did you set the default gateway on the devices?

If you don't use a router, you need to set the default gateway manually.

Just striving to develop myself while helping others.

Hello, yes, the devices have the vlan interface set as their gateway.

192.168.20.1 for the 20 Vlan and 192.168.30.1 for the 30 Vlan.
