Unable to traceroute from MT

RouterOS General

Hi,
I have weird problem with MT CC1036 v4.64.6
I am unable to traceroute from MT:

[admin@MT] > /tool traceroute 8.8.8.8

 5                                  100%    2 timeout

But the host sitting behind MT has no problem doing that.

Seems to be a firewall issue. Maybe you are blocking UDP traffic.
I had a similar case in this thread: http://forum.mikrotik.com/t/traceroute-problem-in-one-lan/140132/4

While bare Linux traceroute uses UDP by default, RouterOS uses icmp.

But yes, firewall is the most likely cause, but policy routing may be another one. Without seeing the configuration, nothing more specific can be said.
