    I don't think the Virtual Address will pass ICMP (only TCP and UDP).
    If the BigIP doesn't have an existing connection or a VIP with the
    IP:Port that the packets are coming in one, it will ignore the packet by
    You would probably need to turn on "IP Forwarding", then the BigIP will
    just route any packets that don't have an assiciated VIP. Depending on
    what your full topology looks like, you may not want to do that. If you
    did turn on IP forwarding, you could always add in some rules and
    filters to block unwated traffic, but it could get pretty complicated
    real fast....

            I have tried to set up the LB so that my boxes behind the LB can
    ping, ssh, telnet and ftp.

            But, I cannot seem to configure it properly.


            Is there any tutorials out there?


            My set us is very easy:


            LB has 2 nics configured with (external), (internal)

            The internal nic is plugged in to a switch and a single box
    ( is connected to the switch (for now).

            I configured a pool with my single box, then configured a
    virtual server with

            I can hit the web server running on the box and ssh into it, but
    cannot ping anything outside the 192.168.10.x network.
