Traceroute on Linux and Windows platforms typically use different packet types. IIRC, tracert uses ICMP 8 (ping) whereas traceroute uses UDP. My flavour of traceroute accepts the -I flag to force ICMP 8. My version of traceroute also has the --mtu option, which tries to determine the MTU for the route being traced. It looks perhaps like the firewall for interactivebrokers (IP 208.192.181.62) *may* be blocking too many ICMP control message types - including the MTU/Fragment messages.
