Clarification running multiple LAN's

  • A little while back, I installed pfsense 2.0.1 on a Watchguard x1000 and it has been running great.  I work from home and currently my setup is like this: Dual WAN - Comcast cable and AT&T DSL in ports 1 and 6 and lan 1,2,3 and 4 in ports 2,3,4, and 5 respectively.  Lan's 1 and 2 both use comcast as their gateway and 3 and 4 use AT&T.  These are all plugged into a Dell Poweredge 2848 switch which is vlan'd pretty evenly with about 12 ports to each lan.

    What I need clarification on is how traffic is routed between vlan's, since I did no vlan setup in pfsense.  I have a network file server (synology ds1010+) that resides on lan 1, but I need all four lan's to access it.  So I added rules allowing traffic from each lan to the ipaddress of the synology box.  When a device on Lan 2 needs to access the file server, is it doing so directly on the switch with gigabit capabilities or does all traffic pass up the pipe to pfsense and then is routed back down the lan 1 interface, in essence limiting me to 100Mpbs speeds?

    It completely depends on how your switch is configured and whether it's a layer 3 switch.
    I'm not sure how you are using VLANs, do you have other switches and vlans?
    It seems to me more likely that you simply have your switch ports divided into 4 groups (internal vlans) in which case routing between subnets does go via the firebox.


    Edit: The Dell PowerConnect 2848 does not appear to support layer3 routing.

    It goes to the Firebox handling all traffic….

  • The PowerConnect 2848 is strictly a layer 2 switch all routing will be fed up stream and come back down to the switch ports.

    Here is a User Guide for the switch for further reference.
