In case anyone else is interested, we're trialling using iptables to
increase the TTL on those multicast packets so that they'll get routed.

(Sorry I meant to add this in my previous email)

Here's the rule:

iptables -t mangle -A OUTPUT -d <multicast address> -j TTL --ttl-set 128

Where <multicast address> is replaced by whatever your cman is using (you can
get an idea of this using netstat -gn).
