So, I have two interfaces from different ISP's and I'm trying to monitor my connection using mtr. This is the command I'm currently trying to use:

mtr --no-dns --address $MY_REAL_IP_HERE $A_DESTINATION_IP

Unfortunately this is not going though the interface I want it to. At the moment I have eth1 and ppp0, and I would like to monitor only ppp0. Any ideas what I'm doing wrong?

Actually, the command above is perfectly correct. Unfortunately at the time I asked the question the routing table was a bit broken. So the actual route was going though the wrong IP address even with the --address argument.
