I read in several forum posts that the ability to disable and enable an interface was slated for a v18 feature set, but I do not see it - so I suspect it was not implemented? That would be a pretty big step back to still be missing after 4 years of planned development. It was a basic feature of the v9 UTM that I had to use somewhat frequently when Comcast loses its mind. Now it seems like the whole appliance would need to be rebooted to resolve a communication issue? (Note - I do have remote/console access to my Sophos, Comcast provides no such facility for the cable modem and thus it isn't resolvable as a Comcast problem (reboot the Comcast box to re-establish communication) but I could do similar with an interface reset).
