To be honest: if you are no technical expert get someone who is and have him set it up for you. If you want to use VLANs for security reason you don't want to mess this up. Managed switches are complex devices. I generally tell people: If you think the web interface is too complicated then the device is too complicated for you.

The following is based on this demo gui.


VLANs are configured on the VLAN Management tab.

First create the necessary VLANs on the Create VLAN page. Pick some VLAN numbers and assign some description short names to them, e.g. VLAN 10 Account, VLAN 20 Employee, VLAN 30 Guest. Remember to press the Save Settings link at the bottom of the page before continuing to the next page.

Change to the Port Setting page. Basically all "normal" ports which connect to desktops and client devices should be in Access mode. The only port you must change is the port which connects to the SonicWall. Set the port (e.g. port 48) connecting the SonicWall to Trunk mode. Again Save Settings on the page before changing to the next page.

There are two ways to make the VLAN-port assignment. Either you assign ports to VLANs (i.e. you select a VLAN and then say which ports belong to this VLAN) or you assign VLANs to ports. Usually the ports-to-VLAN is usually faster and easier if you have a limited number of VLANs.

Thus, press Ports to VLAN and then select the first of your created VLANs, e.g. 10.Now make all ports which should go into this VLAN untagged members of this VLAN. For example, if port 21 is connected to a desktop which should be in VLAN 10, then you select the radio button in column 21 in the row "UnTagged". For your first VLAN 10 select all the ports which go into VLAN 10 and set them untagged. In addition make the port connecting to the SonicWall tagged member of this VLAN, e.g. in column 48 select the radio box for "Tagged" which should be available on that column.

Click Save Settings then select the next VLAN and do the same: make all ports which should go into VLAN 20 untagged member of VLAN 20 and add the SonicWall port as tagged member.

Go through all your new VLANs and do it for each of them. Remember to save settings before switching VLANs in the web interface.

That's all. Now each client/desktop is assigned to a specific VLAN and communicate with all devices also assigned to this VLAN. All devices can also talk to the SonicWall. None of the client/desktops can communicate with any device in a different VLAN, at least not if the SonicWall routes between them.

Now you have to configure the port on the SonicWall which connects to the SRW in the same way you have configured the port on the SRW, in the above example like port 48. Using the example, the port connecting to the SRW must be set into "trunk" mode (or how they may have called it). Add all VLANs you have created as tagged members, i.e. VLANs 10, 20, 30 must be tagged members on that port. In addition add VLAN 1 untagged or set VLAN 1 as "native" VLAN. You have to check the SonicWall documentation on how to configure that exactly.

In addition, you must assign distinct IP subnets to each of the VLANs (e.g. for VLAN 10, for VLAN 20, etc.). If you want those VLANs to have internet through the SonicWall, the SonicWall must provided a routed interface in each of these VLANs (e.g.,, etc.) Anything else, too, must be configured on the SonicWall.

Remember: a standard desktop or client device can only be member of a single VLAN. The port to which it is connected must be in access mode and untagged member of this single VLAN. A normal desktop or client device (like a printer) cannot be member of multiple VLANs. That's not possible. These devices do not support 802.1q.

That's in short the basic steps. If you are not an expert on the SonicWall, too, you'll have a hard time getting this working. ....

Hi Piji,

I will close the forum as i have found my answer. The answer is no. srw2048 cant assign subnet on vlan. I will give you no point as you basically copy and paste from other forum and that answer is for another question which related to sonicwall
