Sonicwall to Cisco VLAN trunking

Posted on 2011-04-23

I have an IBM Bladecenter with integrated Cisco switches in my datacenter.  If you aren't familiar with the Bladecenter, all you need to know is that ports 1-14 on the Cisco switch are connected to blades 1-14, and it has four external ports for connections to the outside world.

I'd like to setup a scenario where I add a Sonicwall NSA 2400 firewall to the configuration.  I would sell my customers a service where they could do a site-to-site VPN from their location to my Sonicwall in the datacenter, and access their blade server over a private VLAN.

So, I would need the Sonicwall to terminate the site-to-site connection, and place the traffic from that connection on a VLAN that is sent out to the Cisco switch in my bladecenter.  Moreover, I would want to do this with several customers in the future.

Question is, can the Sonicwall "trunk" all those VLAN's out one interface or does it need a dedicated interface for each VLAN?  Would you do anything differently?

    I don't know if I'd do anything differently, but with the 2400 you can setup multiple vlans on a single interface. You'd create a zone for each interface, as I assume you want to segregate that traffic, then add a new interface to an existing interface and give it a vlan ID.
