Sideband connection to self (i.e. VIP initiating the connection)?

Does anyone know whether it's possible to make a sideband connection to the same VIP the connection is being initiated from? I'm not seeing any errors, but I'm not getting a response (payload) either.

    what version of code are you running? if its under 11.5 then you need to specify what IP the LTM will use for sideband otherwise it will try to use 127.0.0.1. We have a rule that uses sideband connectivity but it uses a another vip for sideband connectivity and works fine. Not sure if you can use the same VIP.

    We're still stuck on 11.3. Calling a VIP by name works, but only if it's not the VIP that initiates the sideband connection. I'll see what happens if I use the VIP's IP-address instead.

    We use a static variable to tell the F5 to use these addresses as the source to connect tothe sideband VIP

    array set static::SIDEBAND_LIST {
    ltm1.com    "x.x.x.x"
    ltm2.com    "x.x.x.y"
}

    we also all the
