Using a single Layer 3, (Dell 3448) switch.  I've created two VLANS:

How can I attach to my TZ170 router?  It doesn't appear to support trunking?

    Create a 3rd vlan with just 1 access switchport and the firewall connected to that vlan.
    Use the L3 routing functions to set the default gateway to the Sonicwall.

    So, can I run all VLAN's on the same subnet, i.e. or do I need to further subnet, i.e., and and still connect to the TZ170?

    lrmoore, in using your suggestion in the first response, I'm assuming that this single access, switch port will "not" be trunked to the TZ170?

    Accepted Solution

    VLAns need to be separate subnets.
    Correct, no trunk to TZ170
