I'm trying to set up a configuration in which I have a SonicPoint at one end of a building connected to a series of switches that ultimately leads to a SonicWALL at the other end of the building. SonicWALL has told me that I'll need to use VLANs to achieve this. They want me to configure a chain of traffic (SonicWALL ---> switch 1 ---> switch 2 ---> switch 3 ---> SonicPoint) where VLAN 2 is tagged and another dummy VLAN (I've used 5) is untagged. Here's my concern - all regular network traffic is passed over the default VLAN (1), and this is currently untagged on all ports on all switches. If I change the connection between the switches to VLAN 5, will this affect normal network traffic?
Thanks in advance!
