The address is unallocated/unassigned.

You're posting with windoze outhouse express. The incredibly broken
tracert that comes from microshaft uses ping (ICMP Type 8) rather than
UDP packets that the original traceroute uses. Thus, anyone blocking pings
is going to break the function tracert depends on. However, as there is no
network assigned to use the address space between 140.205.0.0 and
140.207.255.255, the first router with a clue is going to return an ICMP
Type 3 Code 0, 1, 6, or 7, saying you can't get there from here.

>So who is it? That address is trying to VPN in because of the log's we see.

Post the _exact_ logs. If you can run a sniffer like 'ethereal' or 'tcpdump'
or have a passive fingerprinting application like ettercap, NIDS, n0t, natdet,
p0f, or prelude-ids, post the packet headers or signature data.
