    Got it! However, how do I resolve the issue where I cannot add IP's to
    my second subnet. Says I am using incompatible IP and mask (see recent
    msg). This is one stickler in the whole thing for me. :-)
     
    Cheers.
     
    Chris.

    You can do this, create a virtual server 0.0.0.0:0/your-vlan
    just assign "your-vlan" to the 0.0.0.0:0 virtual and attach a pool (your
    pool could just be a single gateway).

    I am indeed.
    What I don't really understand though is how to configure each VLAN to
    have a different default gateway.
    VLAN "external" and VLAN "public" are both on the 2.2 physical interface

    to the Internet. They are essentially just two different public IP
    blocks that I would like to be able to bind virtual server IP's to.
    Can this work? I would like the BigIP to use a different default gateway

    depending on which VLAN and VIP was accessed.
    Thanks for your help.
    Chris.

    Chris,
    This should work--are you giving them vlans different names?

    I am running BigIP 4.2. My physical 2.2 interface is connected directly
    to the Internet. The only VLAN on this interface is called "public" and
    has a network address of xx.xx.31.0 subnet mask 255.255.255.0.
    I'd like to add a second VLAN to this interface which would have a
    network address of xx.xx.32.0 subnet mask 255.255.255.0.
    I have tried creating a 2nd VLAN but it seems to conflict with the 1st
    one that is defined. I'm sure I'm just doing something wrong. Basically
    I want to be able to set up new virtual server IP's on either VLAN.
    Both network addresses are available to me through my Internet
    connection, just need to find out how to make BigIP see them both as I
    seem to only be able to get one VLAN working at a time. Perhaps I am
    misunderstanding what tagged and untagged interfaces mean.
    Any help is appreciated.
    Cheers.
    Chris.
