Freenas with multiple networks on multiple vlans.

Hi

I've been trying to get freenas working with my multiple vlans but I'm not convinced it's working how it should.

I've the following:

Vlan 1 (default), which is home to the 192.168.1.0/24 network running servers etc, and then, vlan 4, running 192.168.2.0/24 network, with PCs etc.

Ports for freenas is in vlan 1, but tagged with vlan 3 also.

The physical interface has nothing on it, I created two vlan intefaces both with the same parent interface (em0), I'm not sure if this is correct, but essentially, I added two vlans within the vlans tab, after this I can could add an interface with the nic as the the vlan I created, so I did this and removed any ip address information on the em0 interface.

ifconfig on the box looks like:

Code:

em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO>
        ether 68:05:ca:23:7f:40
        inet 192.168.1.108 netmask 0xffffff00 broadcast 192.168.1.255
        nd6 options=9<PERFORMNUD,IFDISABLED>
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
vlan1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=103<RXCSUM,TXCSUM,TSO4>
        ether 68:05:ca:23:7f:40
        inet 192.168.1.10 netmask 0xffffff00 broadcast 192.168.1.255
        nd6 options=9<PERFORMNUD,IFDISABLED>
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        vlan: 1 parent interface: em0
vlan4: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=103<RXCSUM,TXCSUM,TSO4>
        ether 68:05:ca:23:7f:40
        inet 192.168.2.7 netmask 0xffffff00 broadcast 192.168.2.255
        nd6 options=9<PERFORMNUD,IFDISABLED>
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        vlan: 4 parent interface: em0

With this setup, I seem have a few connection issues. I did observe that I can see traffic for 192.168.10.0/24 when i run:

tcpdump -ni em0 vlan 4

So I think stuff is leaking into the wrong vlans etc.

You appear to have an IP address configured on em0. That's not going to work well especially since you have an overlapping vlan1 also on that net.

I do not get what you intend when you say "tagged with vlan3 also." A vlan is a virtual LAN, and a packet cannot have multiple tags.
