You could use traceroute with a "-T" option (to try a TCP
SYN probe),
but you also need to specify a port you know the machine is listening on
but is NOT blocked by the ISP. Most ISPs don't block SSH on port 22, so
a "traceroute -T -p 22 <ipaddress>" may succeed IF you have sshd
listening on port 22. No guarantees, however.
You can also use -I to make it use ICMP ECHO for the probes, but that
requires root.
