Multi VLAN single port
Hello, I have an issue with configuring three VLAN networks with IDs 1, 20, and 30. The router's default VLAN is set to VLAN 1, which connects to a 16-port unmanaged switch TL-SG1218MP. When I connect a new device, everything works fine, and the DHCP server assigns an IP address in the VLAN 1 subnet. However, if I manually assign an IP address from the VLAN 20 subnet to the device, it loses internet connectivity.
ACL (Access Control List) is configured to allow traffic between VLANs, so that shouldn't be an issue.
Do you have any recommendations or insights on how to resolve this problem?
Hi @Darius_S
Thanks for posting in our business forum.
This has nothing to do with the ACL. Multi-VLAN is a trunk.
You might need a switch that can process 802.1Q VLAN. This switch with a LAN port on your router, only provides one single VLAN(untagged) and allows only one to work.
This unmanaged switch is plug-and-play and just forwards what VLAN it receives. Read the VLAN guide I wrote on the switch page.
