VIP not reachable

Hi,

I have following simple virtual server on a 11.5.1 system;

ltm virtual /ITSS/live-fisheye-temp-vs {
            destination /ITSS/2.170.236.64:8060
            ip-protocol tcp
            mask 255.255.255.255
            partition ITSS
            profiles {
                http { }
                tcp { }
            }
            rules {
                _sys_https_redirect
            }
            source 0.0.0.0/0
            source-address-translation {
                type automap
            }
            vlans {
                EXT-WIN-11
            }
            vlans-enabled
            vs-index 592
}
`
`

And the VIP:

``ltm virtual-address /ITSS/2.170.236.64 {
            address 2.170.236.64
            mask 255.255.255.255
            partition ITSS
            traffic-group traffic-group-2
            unit 2
}

ping works, but a

telnet 2.170.236.64 8060

keeps stuck at 'Trying 2.170.236.64...' I tried re-enabling the VIP and ARP status, but to no avail. I can reach other addresses in that range and on that traffic group. A

telnet 2.170.236.64 8060

on the bigip works. I see no response back to my computer or to the gateway using telnet. The gateway has the correct VLAN mac address for the listener.

Ideas?
