Draytek 2710 / D-Link DGS 1210-48 VLAN Problem
Posted on 2014-03-25
We have a 48 port D-Link 1210-48 port switch which is configured for three VLANs as follows:
VLAN 1 Internal - Ports 1 to 36 untagged
VLAN 2 Warehouse - Ports 37 to 44 untagged
VLAN 3 Public WIFI - Ports 44 to 47 untagged
Port 48 tagged for VLAN1 and VLAN2 and has Draytek 2710 router in it.
All VLANs working fine. There is a public router serving three access points plugged into port 47 and is working fine. Public users can access the Internet without issue.
The problem appears to be with the Draytek. We have VLANs enabled on it, P1 enabled for "VLAN0" which we understand is tagged across the network as 1, and "VLAN1" which we understand to be tagged as 2. P2, P3 and P4 are all taged as "VLAN3" as we understand that they need to be assigned to something. P1 is plugged into Port 48 on the switch.
The Draytek is set up for DHCP, but serves no IP addresses to the network, for either of the VLANs that it is supposed to. Also, if we assign a relevant static IP to one of the clients on either VLAN we cannot ping the Draytek. If we turn wireless on for the Draytek, we can connect fine to the Internet through a DHCP supplied address.
Does anyone know why we would have a problem with the VLAN setup? It all seems straightforward enough to configure but something just isn't right.
