The traceroute problem regarding maximum reachable hops ( i.e. 11 hopes ) may be since the Unix/Linux/OSX traceroute uses UDP to send the requests. The first request is sent to a particular port (33434), with a ttl to tell it how many hops to go to. The ttl starts at 1 is incremented as it tries the next hop, also the port is incremented (up to 33465). It looks like the first few UDP ports are enabled and then they are blocked. The Windows traceroute uses ICMP to send the probes.
