To close this thread for the benefit of readers of the archives, the problem was that the routing table on the main gateway did not have an entry for the 192.168.2.0 network. All the server machines had been shut down and rebooted together because the UPS batteries had to be replaced. It seems that the gateway machine came up before the internal router and was unable to add a route for 192.168.2.0 because the router was not yet responding.
