Dear Mike, Many thanks for your very fast reply :)
All my nodes are on the same switch, but we are using software firewalls. The cluster is trying to use the second ethernet port which is plugged into a dedicated switch, which is "trusted" and not supposed to be firewalled but I have a hunch that the multicasting thing is not going over that port, and I am not sure how to force it to (nor am I sure if it matters). However, could you confirm how you forced ganglia to use your tunnel - particularly for the multicast packets?
