hey Simon, I still had intermittent problems with this and didn't have time to look at it until the holidays with wireshark. Pretty clear what was happening with QuFirewall. you also need to also allow 239.255.255.250 for the multicast on 1900 back in. Now the Firewall on or off behaviour is immediately bringing up the minimserver on all devices.
