Test access sourcing from float

To test firewall rules we telnet to the pool member's service port, which proves access for the self IPs, but not for the float. Anyone know how to source from the float?

    # telnet -b floating_self_ip destination_ip
    -b hostalias
        Uses bind(2) on the local socket to bind it to an aliased address (see ifconfig(8) and the ``alias'' 
        specifier) or to the address of another interface than the one naturally chosen by connect(2).  This 
        can be useful when connecting to services which use IP addresses for authentication and 
        reconfiguration of the server is undesirable (or impossible).

    Be aware of route domains; https://devcentral.f5.com/s/question/0D51T00006i7apM/telnet-to-server-from-f5.
