I am happy to implement BK’s suggestion to limit the setting up of gateway endpoints that fall within the 44/8 range to co-ordinators.

I am also happy to go through and remove any currently empty/incomplete gateways. Perhaps I could also setup a cronjob that purge such entries on a regular basis, e.g. any that are over a week old with no subnets?

I can implement the above fairly quickly if that is what is wanted?

I would certainly appreciate that. Even better would be to implement the addition of a new property 'advanced user' (initially copied from 'co-ordinator' and settable by you and Brian) and also the re-introduction of checking the subnets being routed by the gateway, depending on that property. But even with only the changes mentioned above we should have some improvement in reliability.

Brian: I also wonder if the return if ICMP unreachable messages on RIP broadcasts is somehow logged or stored in a form that allows gateways that have done this for extended periods of time to be automatically disabled or deleted.
