This was my first real adventure into the land of vLans. I had setup very basic port-based setups before but this scenario required an The client runs serviced offices and required that the offices could share the internet but would not see each other on the network.
The clients themselves use part of the office and had the requirement for several more ports than the other offices so it was allocated more ethernet ports on the switch. Normally if your client can afford it, such a scenario would be played out using High-end Cisco gear.
The outcome we looked to achieve is shown on the right. If someone could tell me why this has to be done I would be interested to know. In any case we mapped vlan 10,20,30,40,50 to port 4 and allocated the subnets of LAN as shown in the image. You could set priority to the vlans if you want to prioritize certain traffic. We have not set that here. Then we enabled the various subnets under general setup and enabled DHCP on all of them.
If you wanted to enable inter-lan routing you could do so here. Here we gave it The Draytek Router is Before plugging the two devices together, you are going to want to configure the GST. By default if it cannot find a DHCP server, it will use the address In the simplest of LAN topologies, you have a single physical network and everything on that LAN can communicate with any other device. A VLAN can also provide additional security by ensuring that physical networks only carry necessary data, perhaps omitting more sensitive data.
A VLAN can be physically separated or separated by differential labelling of datagrams. It's important to remember that a VLAN is not the same as a different subnet e. Subnets provide IP addressing space, or logical departmental or network numbering but do not separate the networks or provide any security. If you just have multiple subnets, any device could have more than one IP address or connect to either subnet as both are available on the same physical network.
This is a common application as it makes it easier to keep track of your VLANs. There are two main types of VLAN; port based or tag based. They can be used in combination with each other. VLANs can increase both network efficiency and security. A port based VLAN is one where the physical ports of an Ethernet switch such as the one built into your router are separated so that traffic does not pass between chosen ports.
For example, if you have one PC plugged directly into each port on your router. Restrictions can be per user, per PC or universal. Using DrayTek's GlobalView service, you can block whole categories of web sites e. A free day trial is included with your new router. The ethernet port can connect to a second ADSL modem e. Vigor , a cable modem or any other Ethernet-based Internet feed. Load-balancing or failover supports IPv4 only currently.
Internet Traffic will be temporarily routed via the secondary Internet access. When normal services is restored to your primary ADSL line, all traffic is switch back to that. In addition you can instead connect a compatible analogue modem to use analogue dial-up connections for failover in the event of your broadband failing. In its simplest form, each of the four Gigabit LAN ports can be isolated from each other, for example to feed four different companies or departments but keeping their local traffic completely separated.
The VLANs can each be tied into each of the different IP subnets that the router may also be operating, to provide even more isolation. Each can be independent isolated or common able to communicate with each other. This is ideal for departmental or multi-occupancy applications. The Vigor has built-in user management which allows you to provide internet access to users based on their own unique login stored in the router, or on an external Radius server. Accounts can be restricted by schedules or maximum usage times but also any other aspect of the firewall or content filtering can be applied on a user-by-user basis.
For example, a sales department might not be allowed access to social networking sites except at lunch time, or in a school, teachers and staff have more access permitted than pupils. This works with Wireless WiFi clients too so is ideal for guest or temporary access as users can be isolated from the rest of the company LAN.
The Vigor Series 'n' models feature In addition, This offset arrangement of aerials provides offset paths between hosts so that interference can be overcome. The Vigor n and Vn includes Dual-Band technology. Most commonly, WiFi operates in the "2. Everyone has to share the same bandwidth, and The Vigorn and Vn models can be switched to use the 5. If your laptop of wireless device does not support the 5. The Vigor Series provides several independent levels of security including encryption up to WPA2 , authentication The Web interface lets you see how many and which clients are currently connected as well as their current bandwidth usage.
An 'instant' block lets you disconnect a wireless user temporarily in case of query. The Vigor wireless versions also allow guest access with password protection so that visitors can use your WiFi access, but only with a password which you set for them. When the user connects to your wireless LAN, they are firstly presented with your login screen before any Internet access is permitted. This is in addition to any encryption system you have running.
The Multiple SSID features enables you to have up to four distinct or common virtual wireless access points. For example, you could have one for company usage, with access to your company LAN and another for public access which allows internet surfing only.
Setting up wireless security is made easier thanks to the WPS feature WiFi protected setup whereby your client PC can get it's security keys by pressing a button on the front of the router. If your laptop PC's built-in wireless doesn't support Click on 'accessories' for details.
