Port Overlapping – Port overlapping can be used to allow access to commonly shared network resources among
different VLAN groups, such as file servers or printers.
Untagged VLANs – Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A
group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on
the VPN Router. Packets are forwarded only between ports that are designated for the same VLAN. Untagged VLANs
can be used to manually isolate user groups or subnets.
PVID - VLAN ID assigned to untagged frames received on the interface. (Default: 1)
If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the interface will automatically be
added to VLAN 1 as an untagged member. For all other VLANs, an interface must first be configured as an untagged
member before you can assign its PVID to that group.
Link Type - Sets the port to accept the frame types: “Access” means the port can only receive or send untagged frame
types. “Trunk” means that the prot can only receive or send tagged frame types.

Click Port-Based VLAN to configure the VPN Router.
Port-Based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address and its
associated port.
When using the port-based VLAN, the port is assigned to a specific VLAN independent of the user or system attached
to the port. This means all users attached to the port should be members in the same VLAN. The network
administrator typically performs the VLAN assignment. The port configuration is static and cannot be automatically
